Step 2: Jacket Requirements
When choosing or making your own jacket, be prepared for the following:
1. The jacket should be made of a natural fiber, like cotton or wool. Cotton is best and will allow you to attach interfacing and will handle heat from your iron well.
2. If your jacket has a lining, be ready to rip it out. Grab a seam ripper and go for it. Try to save the lining if you would like to reuse it after the electronics are in.
