janRN, Maybe put a sticky note on your printer?
I cut half again as many triangles as I needed. That's due to my math abilities... Then I sat down and chain stitched a ton of them, about half, making the seam on the wrong side of the triangle-- making HSTs instead of the larger triangle needed for the hourglass... Talk about being ditzy! lol So, I seam ripped that out, re-sewed them, and now I've got most of the star blocks finished.
