This quilt top has been on a journey. 2 years ago, I won a block draw at a quilting retreat. Everyone at that retreat made 2 blocks. They were large (9") half square triangle blocks, with Kaffe Fassett fabric in one half and white in the other. I loved the fabrics, but the quilt top seemed a bit too simple for my tastes, so I decided to modify it. This was the original pattern.
I've played with this block design a few times now, and it cuts perfectly from the half-square triangle. By cutting all my blocks into 4 pieces, I got two half-square triangles and 2 plain squares from each block. The plain squares were easily made into two 4-patches, and the result could then be re-assembled into Jacob's Ladder blocks.
The quilt top ended up 56x70". I think a border is needed, so I'll have to find a Kaffe Fassett fabric I like for that.
