From Amy Smart, the designer:
The method for making this Christmas tree quilt blocks is quick and fun.
I loved sewing them together into this little patchwork Christmas forest mini-quilt.
These blocks finished at about 3 1/4″ x 4 1/2″
Improv-piecing makes this modern Christmas Tree quilt not only come together really quickly, but makes each quilt totally unique.
There's a free video tutorial by the designer on how to make the blocks.
