Washing flannel
I made 3 memory lap quilts from jeans and shirts that my dad wore for my siblings and myself. My dad passed away unexpectedly in October. I’m going to back them with flannel. I bought a bolt of 8 yards and another piece. I want to cut and make the backing pieces before I wash because I don’t think I have enough strength to manhandle an 8 yard piece.i plan to make it 4-5 inches bigger all the way around. Do you think it will shrink more than that? Should I make it bigger? I’ll wait for some experienced feedback before I cut. TIA
