Double your fun by creating two Cat's Cradle units from each set of squares and rectangles. Trim the blocks with the Cat's Cradle Tool to create perfect triangle blocks without ever cutting a single triangle! Create six different sizes from 1-1/2 to 4 inch finished blocks - the cutting requirements for each is printed right on the tool! Need larger units? The Cat's Cradle XL Tool (Item CGRDH1XL) creates eight different finished sizes from 4-1/2 to 8 inches.
