I was thinking that the triangles could be stitched diagonally on the pressed line and then stitch again 1/2" +/- from the original stitch line. Once you cut between the rows of stitching the result is a pile of HST to use in another block.
This is a great way to diminish the scrap pile. And the triangles would not have to be the same size which might be an interesting result. Also using multiple sized triangles would be interesting to consider. The possibilities are endless. -- Thanks for sharing this site.
