I pre-wash fabric to check for bleeding, to insure a good bond with fusible, to insure even shrinkage, and to check quality of questionable fabric. As my dad used to say, "better to be safe than sorry" :)

Same here I don't wash the fabric ,Iv never had reds bleed onto other pieces but I use good fabric,,,,I do like steam a seam its pricey but works great

I would prewash all fabric to used in applique project to allow for shrinkage of both base fabric and applque fabric before they are fused together. Other fabric that I use for quilt making I do not wash since I want the crinkle look when finished.

I am trying to do free spirit the horse sihoutte and it has raw edges , I was planning to strait stitch on, plus I have wonder under here so was going to use that

Oh, you are opening a Pandora's box!!!

I'm in the wash everything camp!

I've had better luck not washing, lol.

I use steam a seam, sometimes I wash and sometimes not. Just depends on what I am doing. Try both ways to see which is your favorite.

I wash all my fabric. Then starch it, use lightweight interfacing for backing. Works great

please wash....there are soooo many chemicals put on that fabric and most are carcinogens...and the directions for ALL fusibles state to use on washed fabric...

I would rather have my material shrink and/or bleed before I put all that work into it, so, prewash, for me, is preferable.
