Jenny's blog, SewKindofWonderful, has lots of examples of quilts made using the ruler, as well as her tutorials for cutting and sewing. She makes it look easy but I thought I better test it out before cutting into my precious Paris Flea Market fabric stash. First, I cut the curved pieces.
The markings on the ruler combined with the groove for the rotary cutter make it very easy. Then I sewed them together. Jenny's technique does not use any pins. I was skeptical but it worked out just fine. I got the hang of it pretty fast, worked up a rhythm, and got several curves sewn together in no time. And after trimming, I sewed the rows together. The seams lined up perfectly.
This is my test block. But enough testing; it's time to move on to the real thing!
If this works out well, I see a double wedding ring quilt in my future.
