I have a question -- and forgive me if it's crazy, since I'm still a newbie. I'm just finishing up my first quilt ever (Amy Butler's Thea's Puzzle Quilt) and am going to try this one next.
Is it possible to cut the strips of the jelly roll in half? So instead of being 2 1/2" by 40-ish, they'd be 2 1/2" by 20-ish? Then, still sewing them together (though I think you'd have to take a little more control over where you place which piece, since you'd have doubles of each) and leaving the process the same, would that work to make a scrappier looking quilt?
Or, using the cut-in-half pieces again, could you do something like burnsk did above alternating horizontal and vertical squares, but with smaller squares?
Forgive me if this doesn't make sense, but hopefully you get the idea. I'm so excited to try this!
