Question about Tshirt quilts
My niece asked me to make a quilt out of her old college tshirts - which I am happy to do. She dropped of 40 shirts... "washed and ready" she said.
My question is for the very start of the process. I always heard not to use fabric softener before doing the fusible interfacing. When she said "washed and ready" I am sure that she used fabric softener.
Do you think I need to rewash all of these? Or will the interfacing work with these even though I am sure she used softener??
What do you guys think?
