The Last Clue!
- Lay the “10” and “2” Ruby blocks side-by-side so the Topaz strips form a border along the left, top, and right of the two blocks.
- Slide these two blocks apart and place a Diamond block between them, with the Topaz strip at the top. Sew the Diamond block between the Ruby blocks. Repeat with the “4” and “7” Ruby blocks. Make 2 rows.
- Lay out the two remaining Diamond blocks with the C1 edges touching in the center. Slide the blocks apart and sew the Emerald block between them.
Sew the Diamond/Emerald row between the two Ruby/Diamond rows, keeping all of the C1 edges in the center.
