I've had excess dye or bleeders from brown, black, green, blue, purple, red, orange, and YELLOW fabrics. By the way, some yellows can be quite tiresome to try to get rid of.

As Lori S said - each quilter develops his/her guidelines for fabric prep and what his/her comfort level is in using 'straight from the store' fabrics

PS - I do not rely on the brand or the source - I've had a Moda red spill color, I've had inexpensive no-name fabrics from WalMart that seem to be completely colorfast. I've had VIP reds that are very colorfast. I've had some VIP reds that have excess dye. I can't tell by looking.

The very first quilt I made had fabrics which shrank when first washed. The cured me. I pre-wash every piece of fabric that comes in my door. Then I don't have to ever worry.

I do wash fabric but not always, when I wash fabric or any thing especially jeans, I add vingear this keeps the bleeding away.

I wash and iron every piece of fabric before I use it. Works for me.

I wash all my fabrics, and use Retayne for anything I think might bleed. By the way, I was just at Joann and they were out of Retayne, so I got the Rit version. Anyone ever try that before? It was $3.99 for 8 oz. Since I was buying red fabric, I didn't want to take any chances on going completely without, but I've never tried this brand before.
