I have only made a few bed size quilts for others...most "gifts" have been tablerunners, placemats...
i don't wash any quilt I have finished. I don't use glue, starch, know all my seams are secure, don't drag the article around,and have checked any suspected fabric for bleeding. But, I also know that the recipients are allergy-free. When gifting I simply inform the recipient on "How to wash". When I did knit or crochet, those things did not get washed either. Nor do I pre wash purchased apparel.
