You are not dumb. This is a new way to make a quilt. The process mentioned in this topic is taking 2-2 1/2" strips and sewing them together. Take another 2-2 1/2" strips and sew them together, too. Take both sewn strips, right sides together and stitch the outside seams. This makes a tube. Take your square ruler and place the 45šline on the stitching line and cut to even up the cut and make it ready for the triangles you will be cutting. Watch the tutorial on Cozy Quilts.com and Missouri Star Quilting Co.com to see the placement and cutting of the strip. When you open up the cut triangles, you have a square. You can vary the way you make the block simply by the placement of how you place the end of each square. This is great for scraps, I did one in batik remnants and just love how it looks like you did a lot of work when you didn't.
