While I was cleaning out drawers I found a heap of 3.5" strips that needed dealing with, along with containers of leftovers from two projects.
I'd been thinking of doing a Plus quilt, they are everywhere at the moment, and this quilt plan of Mary's came to mind. She is stitching it as nine-patches and spacer strips, but it can be pieced entirely out of strips and squares. This would be a good pattern for my odd collection of leftovers; I can strip-piece the long scraps, and just sew squares onto the already cut pieces, so it should use up all the leftover bits.
I sewed several strips together, cut them into 1.5" slices and threw them on the design wall. The dark Plus signs float on a light background, and there are no seams to match. Cool. They don't look like normal Plus signs now because of the seam allowances, but they will once the rows are sewn together.
