I was amazed at how "simple" they were. Time consuming - yes, difficult - no. I owe some pics to some people who provided instructions both on this board - just completed the quilt this week. The main things I learned: get a scalloped tool (Quilt in a Day or Terry Clothier (I used Terry Clothier); watch a video you can find on YouTube about scalloped edges (Quilt in a Day tool); stitch the scalloped edges down at the very edge before cutting; use the exact same color thread as the binding
Here's the link I used to make my first block
This quilt block is a common block and has many tutorials out there telling you how to cut out the pieces carefully and piecing them together.
Well with my Cut Down Method it reduces the pattern to a 9 patch. My method uses 4 Boston Blocks / 4 HSTs cut out my way and the center is a Combo 4 patch cut out my way.
I used a 3 1/2" template and the finished size is 9 1/2". If you want to make a 12 1/2" quilt block use a 4 1/2" template.
