I’ve been searching the internet to find quick ways to make HSTs. I want to demo this technique at my quilt guild. The one I saw Jenny Doan demo, by far is the quickest. She used a light and dark 5″ square. She placed right sides together. Then she sewed a 1/4″ seam around the entire block; sizes can vary. Then she cut the square on the diagonal; opposite corner to corner; making four HSTs from that square. Many quilters use this technique. The photo below shows the steps.
