I am going to attempt a Tumbling Block quilt. I have a 60 degree diamond ruler that I picked up at Joann Fabric. I will be piecing the diamonds together by machine. In the past I have dabbled in hexagons, and found that inset / y-seams are very tricky, so I put it aside. I don't want the same thing to happen with this project, so any and all tips are very welcome. :) Thanks in advance.
