I'm trying to sort all this about "string" quilts and foundation piecing out! New terms to me: "strata"=the pieced blocks, right? "Lasagna" quilts=basically a jelly roll quilt, right? I've wondered if using e.g. muslin as a foundation would make the quilt more bulky once you add batting and backing? "Flip and Stitch" basically same as string piecing but string pcg are strips in a row on the backing and F+S can have the strips arranged around a center focus fabric? There are two threads about baby quilts I love that say they are basically a crazy quilt block using the flip & stitch technique: Focus Fabric from a Scrub, and Finished! by weasier22. I finally found one or two tutes on doing them this way or I'd never have figured it out myself! I hadn't been grabbed by string etc. piecing but am beginning to be hooked in! So many questions, so much to learn! And about using used dryer strips as backing, I'm going to have to quit cutting them in half to be frugal and leave them whole! Whew!
