Please count me in too. Made the triangle template and made one block to see how it would go. Already have my strings, a year or so ago I got fed up (read overrun) with my scrap problem so I took the time to just cut them into strips, didn't really measure just eyeball cut. I had already sorted all scraps by color so keeping the strings/strips color coordinated was easy. I just stuffed them into zippered bags.
( I have a tiny OCD problem about some things). Have cut all but 20 or so of the 8.5 x 4.5 foundations, and when I get the triangles cut, watch out.
