I pre-wash my fabric before I use it.

In my first quilt class, we learned that washing fabric before you start a project is a must! I do it every time.

It's a personal preference. I don't prewash any fabric. Some say they prewash yardage but not FQs. I know why, but I wouldn't want to mix prewash fabric with unwashed fabric. I recommend prewashing any fabric that will be used with batik. The batik has been prewashed, so the other fabric should be too (I always forget this). Whichever way you do it, you should be consistent.

Normally, I do not wash.

I always wash, because so many here have said to do so. I'm too scared not to!

I prewash most all of mine, fqs & larger especially. A few charms packs I haven't, & just made little quilts with them, but I do like to prewash. I use the little lingerie bags for FQs, & cold water, gentle cycle, a little laundry soap & a little Downy. Then dry on low. Then I just fold it all nicely, & press as I use it. I use the color catcher sheets to if I even think something might run, but most often, nothing does. I recently started using some of that Best Press, when I have to press any fabrics & am finding I really love that stuff!...

I wash all my fabric as soon as I get home from the shop. that way I don't have to guess if it is washed or not!

I wash. I have had colors bleed . i don't want to ruin another quilt

I don't wash until the quilt is done - unless it is a dark batik - then I pre-wash to make sure I get the extra dye out so there will be no bleeding

I learned the hard way. I will always wash first since I have had the backing bleed thru to the front of a huge queen size quilt.
