Thanks, Butterfly!
I'm glad to hear that "poly thread" is not a scatalogical phrase <g>
Ummm... I don't ever prewash. I can't imagine ironing all that yardage, I love the crisp feeling, and I love the quilty wrinkles after washing the finished quilt. That said, I DO use Synthrapol if there's any question about bleeding...and I DO keep my fingers crossed.
It's probably part of my need for instant gratification. People who do pre-wash impress me...
