Me, I just sew bits of 1 1/2" in one long strip...then cut about 11" before I sew the 10 rows together for a block. I'm working on a second quilt now. When I get 10 11" strips I layer them atop each other and roll them in a flat ball and store them in a plastic container. I keep tally on a piece of paper of the number of sets of 10 I have rolled...have 17 balls right now or enough for 17 blocks so more than halfway through for a 5 x 6 setting if that's the size I want this time. This is a great mindless sewing project.
As far as heaviness especially on a larger size...a nice piece of minky alone would work fine, too.
