Hmmm, got to go to Joann's today for some Heat and Bond, think I'll look for that little can of Sulky KK2000. Athough I don't need it right now, having just bought the 505, but have an extra coupon...
Yes, you can baste using a spray. No pins, no thread! I LOVE it! I've done several small quilts and table toppers this way. I haven't tried it for a full sized quilt, so can't comment on whether it would hold long enough for that. I've sprayed & layered one day, quilted the next, so know it holds that long, but not sure about over several days?
