This free project is taken from The ABCs of Quiltmaking by Janet Lundholm McWorkman.
The School House block is one of my personal favorites. If you search the web for these blocks, you will discover an enormous variety of quilted styles, from midcentury modern to simple designs built from only four pieces. The traditional School House block featured in The Quilter’s Primer is complicated. There are many pieces of different sizes. Organization at this point will make your life much easier when sewing together these small pieces.
