I bought a 1" hex (acrylic) with the 1/4" seam allowance that I use to cut out my fabrics. I think if I remember correctly, you can get three 1" hexes from a charm. I am working on this pattern that I saw posted by Lynnie. It only takes 3 hexes to form this pattern. I am making a table runner. You might want to do an advance search because there have been many previous posts regarding various types of thread used and other information you may find valuable. Happy hexing!!
