I made this One Block Wonder after I had been quilting only a year or two. Someone's comment about stacking very carefully is important. I put a straight pin through all six layers very carefully on a very small identical part of the fabric design as I go along. Cut width of fabric strips the desired size for triangles, then the 6 triangles. It really is such fun to arrange the triangles and always have the surprise of, "Oh! Look how this one turned out!!" The other important part that someone else mentioned was the importance of choosing fabric. I've thought that Hawaiian prints would be could choices. . lots of contrast and colors. The one you see in these pictures are Asian, which I also love. There are no Y seams. . two half-hexagons that you sew with straight seams. Lots of fun!!
