With all the patterns for Jelly Roll Quilts out there, I find I've fallen in love with strip quilting. I used to use a Square Up ruler and mark my line with masking tape. However, now that I am on my 6th strip quilt, I've treated myself to the Strip Tube ruler and I find I can cut strip pieces really fast and accurately with this ruler (You can probably use any triangle ruler, but I didn't have one of those). I love it!
