Hole-to-hole traditional strand chair caning is probably the most popular and well-known type of chair caning, but there are at least three other types of actual “chair caning” methods and techniques. Do you know what they are?
One very common type of chair caning that was invented and first used way back in the 1870s, is “machine woven cane webbing,” but it also goes by several different names; sheet cane, cane webbing, spline cane and cane panels.
During this caning process, the cane strips are first woven on a loom into “sheets” or “panels.” This fabric-like material is used on chairs that have a routed out groove around the perimeter of the chair seat, where the cane webbing is tamped down into the groove and held in place with a reed spline.
Because the woven cane sheet is held in place with the reed spline, this design or pattern is also known and referred to as “spline cane.” And because it’s woven by a machine or loom in big sheets or panels it’s also called, “sheet cane,” “cane paneling,” or “machine cane.”
Installing cane webbing is a lot easier and less time consuming than its counterpart, hole-to-hole hand caning. In fact, the hardest part of this caning process, is removing the old cane and glue from the groove. But on average, this caning project should take you only about one hour to complete from start to finish.

Step-by-step Instructions for How-to Install Cane Webbing
Difficulty of task: Moderate
Things You’ll Need for this DIY Project:
• chair with a routed out groove on the top side of the seat
• replacement sheet cane
• replacement rattan reed spline
• special spline removal chisels, 1/8″W, 1/4″W or 3/8″W
• utility knife with sharp blades, or SKIL 2354-12 iXO Power Screwdriver With Cutter Attachment
• measuring tape
• basketmaking or regular scissors
• wooden wedges
• white glue or hide glue (do NOT use carpenters yellow glue or super glue)
• large sink, bathtub, or 4-inch diameter x 3 foot long, PVC pipe with cap on end to soak cane in water
Step #1–Remove Old Cane Webbing, Spline and Glue from Groove.
First, cut out the sheet cane from the center of the chair using either scissors, a box cutter or a handy battery-operated Skil mini saw.
Then remove cane webbing, spline and glue from chair seat groove using specially made chisels and a hammer. Then bevel the inside edge of seat opening using a rasp and sandpaper, so the sharp edge doesn’t cut the new cane. And be sure to keep a large piece of the old seat in case you need to match the pattern design or color.
Refer to my previous article on How-to Remove Spline Cane Webbing from a chair seat for detailed instructions and photographs to follow the first step.
Step #2–Measure and Order proper Size Cane Webbing and Spline
Measure cane webbing to be 2″ beyond the groove on all four sides. Also, measure the width of the groove itself and measure for length too, giving yourself about 2-4″ longer than needed for the spline.
There are several different patterns and sizes of cane webbing to suit your needs, but order the specific size spline to fit the groove in your chair.
And if you are replacing the sheet cane in a fancy, Victorian-style wicker chair or rocker, use the “close woven” sheet cane, not the open hexagon pattern. Because the plain, dense, closed pattern will not compete with the fancy, curlicues, loops and other embellishments typical of the Victorian period style.
You can purchase all your materials, cane webbing, spline, caning wedges and tools from my Cane & Basket Supplies Directory™, where there are over 30 retail companies listed and also through specialty online woodworking shops.
Step #3–Prepare the Machine Woven Cane Webbing and Spline
Soak the cane webbing or sheet cane in warm water for at least 30 minutes but up to as long as four hours until very supple. Roll up the cane and soak in your bathtub, sink, a wallpaper tray, or PVC pipe with caps on both ends. Also cut and measure spline to be 2 inches longer than the groove. Spline only needs to soak a short time, so put it in the water as you apply the webbing.

Step #4–Begin Spline Cane Installation Process
Drain or shake off excess water from the pre-soaked cane webbing. Position the sheet cane webbing over large seat hole opening so the pattern is centered and lined up both vertically and horizontally. Make sure you have the shiny side up, which is the correct side.
Then gently tamp webbing into the groove using the special wooden wedges, assisted with light taps from the hammer.
At this point, you might want to remove a few of the outer rows of caning from all four sides, which can ease the application of the getting the cane into the groove.
Step #5–Cut Corners, Trim Excess from Cane Webbing Sheet
Press cane into the groove at back and front first, then press cane into sides so the cane is centered properly. Angle your wedges so they are applying the most pressure to the outer side of the groove, not the inner, just to make sure your wedges don’t cut the cane.
Make small snips in the webbing at each corner to ease installation into the groove and then cut off excess webbing on sides to within 1″ to get out of your way. And if you are working on a round seat, cut at several intervals around outside of seat in the extra overhang.
Step #6–Secure and “Seat” Cane Into Groove
Continue to tamp webbing into all sides of the chair seat groove. Make sure that the webbing is completely down into the groove and that the sheet itself is pulled taught, but not tight across the large center hole. The cane will shrink and tighten as it dries, so you don’t want to install too tightly while it’s wet.
Step #7–Cut Excess Cane from Outer Edge of Groove
After the cane webbing is tamped down along the entire groove, then cut away excess cane webbing from the outer edge of the groove. Use care to only cut on the outside of the groove, not the inside or you will ruin the sheet of cane! When I was just starting out, I made this disastrous mistake! Thank goodness I was a quick learner!
Use a new sharp blade in your utility knife to make a clean cut within 1/4″ below seat surface. Again, going all the way around the groove and only cutting and trimming away the cane from the outside edge of the groove. Watch your fingers too, it’s easy to slice your finger in the blink of an eye…Speaking from experience here, too.
Step #8–Apply Glue to Groove
Apply a 1/8″ bead of animal hide glue or any white, water-soluble glue in the center of the groove, on top of the cane. DO NOT USE CARPENTER’S YELLOW GLUE! If you do, the next caner that works on this chair will be swearing at you because the yellow glue does NOT come out easily. You ALWAYS need to use a glue that allows for easy spline cane removal.
Inserting Spline on Round Chair Seat
Shake off excess water from previously soaked reed spline and press into the groove. If you are working with a round seat, begin tamping and pressing in the spline from the center back. I’ve found it easiest for me to work my way around from left to right in a counter-clockwise direction, probably because I’m right-handed. Try and see which way works best for you.
Press the spline into the groove using the side of a wooden wedge over the top of the spline and then tap lightly with a hammer to push into the groove.
When you get around to the beginning end of the spline, measure both ends so they butt up closely together with no gap in between and mark those spots lightly with your fingernail or pencil. Or make a diagonal or slanted cut to match on each end, whichever looks best to you.
Place a small piece of wood, like a shim or use the flat side of a cane wedge under the spline to cut the ends. Using your utility knife or basketmaking scissors, make either a diagonal cut on both ends as in the photograph or a blunt cut. Press ends into the groove so they lay just a hair under the top of the seat surface like the rest of the spline.
Inserting Trapezoidal Cane Seat Spline
–If you are working on a trapezoidal seat with four sides, you’ll need to measure and cut four portions of the spline. Cut each piece at 45-degree angles on both ends to get mitered corners at each of the four corners.
Then begin pressing in the individual pieces of spline one-at-a-time starting on either the front or back sections first, then working your way around the frame. Lay a wooden wedge on its side and lightly tap the spline on top with the hammer so the spline lays even with the seat surface or just slightly above.
Step #9–Clean Up and Let Sheet Cane Seat Dry
Clean up any excess water-soluable glue spills with a warm, wet rag and your project is done! If you are planning to stain the seat and spline, you’ll want to make sure you remove all the glue, because the stain won’t cover any glue.
Allow at least three days for the cane webbing, spline and the glue in the groove to dry thoroughly before using. Congratulations on a DIY job well done. Enjoy!
Color Matching New Cane Seat to Old
If it’s necessary for you to color match a new chair cane webbing seat to the old, because it is part of a set, then you can use a gel stain or oil-based stain to get a fairly close match.
It’s advisable to let the cane darken naturally on its own if at all possible though because the finish treatments seal the cane making it more brittle. The cane sheet can’t expand and contract with the variations of humidity as well with a finish on it, as without.
And remember too, the smooth, glossy side of the cane does not absorb stain well, nor does a clear finish coat stay well. You will need to first rough up the new cane surface somewhat, using some sandpaper or steel wool (steel wool leaves messy fibers), then apply several light coats of stain until you get the desired result.
Let all coats dry first before applying another. Then either brush on or spray a compatible final finish clear coat. Don’t let anyone sit on the chair until thoroughly dry.
Chair Cane Webbing Installation Helpful Tips & Safety Warnings
• Cane webbing and spline supplies can all be purchased through my Cane and Basket Supplies Directory™ or through specialty online woodworking shops.
• Use only hide glue or white water-soluble glue, do NOT use yellow carpenter’s glue or super glue in groove. It will be almost impossible to remove the next time the cane seat is to be replaced if you use anything BUT water-soluble glue.
• In Step #7 when you’re cutting off the excess cane from the outside of the groove, DO NOT cut cane from INSIDE of groove or it will ruin the cane and you’ll have to start all over!
• The natural glossy side of the cane seat does not accept stain well, so it’s best to let the cane seat age naturally. After about 5-7 years it will turn a dark honey color.
• If you must match the color of the seat to one of a set, it’s best to use an oil-base stain applied by brush, using several light coats. Let dry between applications and follow up with a natural varnish or polyurethane.
• Always use caution when handling sharp tools such as the chisels and utility knives to guard against cutting yourself. But make sure the tools you are using are sharp rather than dull, so they perform optimally.
• If using stain, varnish or polyurethane do so in a well-ventilated room or outdoors. And always wear safety glasses.
• Don’t let anyone sit on the seat for at least 3-5 days so the cane webbing and glue can dry thoroughly.
