I usually prewash and at times was in a hurry to begin a quilt and didn't wash the fabrics and everything worked out OK.
My problem now is that DIL asked me to make her a quilt, she's paying for all the materials and quilting. She picked out a kit from Connecting Threads that has has lots of blues and creams and some cranberry. Fabric feels a little thin, would hate to have it shrink and/or color bleed when she has to the quilt. I could give her some color catchers but will she remember them when she has to wash the quilt in the future? Will the fabrics shrink and the quilt look wrinkled and she won't like? I plan to use Quilter's Dream Poly batting, will that shrink the quilt up a little when it's washed? Think after typing this out I've convinced myself to prewash the fabrics, better to safe than sorry. May in Jersey
