Peaky and Spike are the two triangular shapes that usually convince people they love our templates. The 3" size is in Set C and 4" is in Set D. People have asked for a larger set, and here it is! Set R makes a 5" finished square. The 5" size is perfectly suited for today's popular larger fabric prints, and it doesn't take many blocks to cover a bed. Make dozens of different blocks. In their simplest form, you'll love the many 10" and 15" pinwheels and star blocks you can make. Set R is compatible with Set Q for even more block patterns.
