This is the start of a "Lil Twister" quilt that I'm making as a sample for a class at Kindred Spirits Quilt Co. I have loved this idea since I first saw the ruler on other blogs. There are 2 sizes of rulers, one you use with layer cakes and one you use with charm packs. It's quite simple once you get your base laid out and sewn. You lay out your layer cake pieces in a a combination that is pleasing to the eye and sew them together in rows. You sew a border around and are ready to twist. Use your Lil twister ruler and with the ruler markings, you recut the quilt you have made and resew the squares again. (second photo) As you rotate and sew the new cut pieces, it makes this fabulous pinwheel type block. Once you've finished sewing, add another border around and your quilt is finished. It looks like you've spent hours cutting and sewing and cutting and sewing. I love it...sew much fun!
