Block Genius brings together 200 classic blocks quilters can use to hone their sewing skills, in block exchanges, or to create wonderful block sampler quilts. In this impressive collection, avid quilter and quilt designer Sue Voegtlin organizes the blocks into groups of 2x2, 3x3, 4x4, and 6x6 grids and provides accurate dimensions for each cut so quilters can easily size their blocks for 6-, 9- and 12-inch blocks - making this wonderful collection a joy to make. With the exception of a few that were designed by the author, the block designs are all nearly 100 years old. Some designs are still sewn to this day, but many deserve new recognition and use by today’s quilters. Includes instructions on constructing half-square and quarter-square triangles, flying geese, square-in-a squares and parallel blocks.
