OK, now I'm really worried. I'm a newbie, and just today did the first piecing on a lap quilt done in Bali Pops Watermelon. This is to be a special gift to my Granddaughter for her 8th birthday. I've sewn 93 strips of the Pops to 186 pieces of 1895 'gardenia', an extremely pale yellow. Should I stop now and wash, or what? I can't give her a quilt that might bleed. Help!! Please!!
