I always wash the quilts that I quilt myself, because I use glue basting. Ones that I have had long-arm quilted, I did not wash. I do not like the crinkly look myself. In fact, I iron both front and back of my quilts after washing/drying and before gifting. That really helps get rid of the "used" look. Recipients are always pleased to know that they have been washed already, because it eases their minds about caring for the quilt. And I always prewash my fabrics.
