The Star Dreams Die-Cutting and Embossing Set from Spellbinders features a combination of circular and triangular shapes. Use them on their own or nest the Cut Fold Tuck pieces with their coordinating inset piece. Simply fold the cut-outs, and then tuck the folded pieces to instantly create dimensional designs. Mix and match these with other Cut Fold Tuck dies (each sold separately). These dies are compatible with most leading die-cut systems. The approximate die sizes are: 3/4", 1 3/8", 1 3/8" x 1 1/2" (inset), 1 5/8" x 1 1/2" (border), 2 1/2" (inset), 2 5/8" (border), 3 7/8" x 3 1/8" (inset), and 4 1/4" x 3 3/4" (border).
