Free Quilt Block Pattern
The Four Crowns is a simple four patch with one of my favourite "features" -- that being, it is designed in a directional format. I like these types of blocks because you can create numerous arrangements by using 90 degree rotations of some of the blocks. I generally group four blocks together in a "chunk". You can create all sorts of interesting outcomes because secondary designs start to emerge.
The block is created entirely of half square triangles, in two different sizes.
