I love to buy precuts and this is a pattern that is perfect for layer cake squares and charm squares, or fat quarters! It only requires thirty 10" x 10" squares and thirty pairs of matching 5" x 5" charm squares, plus background fabric. If you have a large stash of fat quarters, you can pick 15 of them and cut your own squares.
As the blocks come together at the end, you will find a secondary pattern is created by the corners--a modern "plus" sign. Some really great quilting in those areas would make this quilt shine ;-)
No special rulers are required. You will also find a coloring diagram in the pattern.
The pattern is available in PDF form on Etsy or Craftsy. Happy Quilting!
