Remember to add the cost of materials to your labor.
Remember that some geographic areas charge more. Charge what the market will bear in your area- based on costs of living. You should always feel comfortable that you're earning a fair wage for your work.
How much should you charge for labor to re-seat a fiber rush or seagrass chair?
$5 per inch, measuring the longest chair rail. Add materials cost to this.
How much should you charge for labor for re-caning chair seats?
Generally, the current charge for re-caning chair seats with holes ("hand caning") is $1.35 to $1.80 per hole in rural areas. Some areas get a lot more: $3 a hole+. Count the number of holes around the entire frame and that's the $ amount that you should charge for labor alone. Check around in your location to see what others charge so that you're not selling yourself short. Add your materials cost to the labor charge.
BLIND caning (also called Continental or French Caning) should be TWICE the charge as regular chair caning, or at least, $1 more per hole than regular caning. It takes twice as long, since each strand of cane needs to be woven and glued in place. It also frequently involved gluing pegs in place.
