Teresa....Please send a picture of the chair you need to work on so we may get a little more info...thanks
Teresa: you'll need to tell us what you are weaving with... cane, fabric, etc
We would love to help!
I'm assuming that you want to weave wicker since it's common on a chair. Here's an article that will give you information on many of the various weaving patterns. I hope this helps you. Wishing you the best.
Please post a picture of your chair so that we can see what you are starting with.
