t-shirt quilt question
I have been asked to make a t-shirt quilt using the t-shirts for both the front, and the back. Has anyone made a quilt using t-shirts for the back also? I will be quilting it on my longarm. I'm concerned about the stability of the back.....will it stretch? What if I use sashing and borders? I use lightweight interfacing on the t-shirts. Would a medium weight interfacing work better for the back?
Any suggestion are appreciated! Thanks for your help.
