Work with your rotary cutters and Marti's acrylic templates to make this versatile family of blocks. Marti especially likes the Rosette (p.32, the Encyclopedia of Patchwork Blocks, Volume 1) because you can practice half-square triangles, Flying Geese style triangles and the Square within a Square technique. There are a host of other similar blocks you'll love making this way. Marti provides the templates needed for class use.
