The Wonky Star Quilt Block is a 9-patch made around a central square. The "wonky" star points are made using triangles sewn on a background square at various angles.
The Wonky Stars Quilt Block is a favorite of mine because it's not a fussy block to make and it's very forgiving. Once you've made a few, you can practically make these on auto-pilot! They use a very simple to learn improv technique. (Click the image below to download the instructions.)
