Instead of card stock I use freezer paper. I cut a strip a bit wider than hex, now this is hex without seam allowance included, then fan fold it, draw on hex from a card stock or cereal box pattern piece, staple in middle of that hex, cut out, cut strip of fabric at least 3/4"wider than hex( allows for turn under..... Then iron those freezer paper hexes spacing across fab. I cut out with scissors giving myself the seam allowance now.......then I take these to sewing machine, set stitch at baste and run a baste stitch around the hex, folding over as I go, then at end of one I do not cut threads, just pull out some and do the next, etc. amazing how quickly you can machine baste those little babies......then when you need cut them apart and whip stitch together.......
