Free Quilt Block Pattern
The Halley's Comet quilt block could be selected as a "study in half square triangles" -- at least in my mind. I'm always thinking as a teacher of quiltmaking, and so I like to instruct with blocks that are not the most commonly used. This cute pinwheel block is a fun one to make.
This five patch block is easy to construct, once you have sewn your half square triangle patches. I like to stitch blocks like this as an uneven nine patch, rather than sewing in five rows of five. I think it makes it easier to sew in what I call "chunks" instead of row by row -- but that is just me, so please use your preferred method and enjoy this striking quilt block.
