The Helena Quilt Pattern from Gudrun Erla uses an assortment of 10" fabric squares in various colors to create this intricate quilt. It features quite a bit of piecing, so it's recommended, but not required that you use Creative Grids
Stripology Squared Ruler (not included) to help speed up the time spent cutting. The Helena is an intermediate skill level pattern and includes five different size options: crib (32"x48"), lap (48"x64"), twin (64"x96"), full (80"x96"), and queen/king (96"x96"). All the directions you will need, as well as a list of fabric requirements, are included with the pattern.
