I decided to SID for now. I think I may wait out the need to quilt the large squares and see how it holds up. I used the invisible thread for both top and bottom piecing. It was a little finagling [word?] to manuever fabric through the small space on a DM but it wasn't too bad. I just roll and fold. I basted it pretty well so I only spread out the area in front of me to be nice and smooth while the area around that looks like a mountain of fabric! Thanks!!!
