This block is called "Arrowhead" it's a sopisticated block made fun by "Anita Grossman Solomon" in her book "Rotary Cutting Revolution" her techique on this was to simplify the block..just by the way u laid it out before u cut..I really enjoyed it and had a lot of black and white to play with!! My 6 year old Grandaughter loves it and her 7th B-day is in 3 weeks..just may be her gift..lol..!! May or may not sash it..not sure,,still playing!
