Blue Onion is the Curve circles Quilt Pattern for a 50" x 70" quilt.
The Blue Onion swirling blocks are made from a variety of contrasting prints.
To change it up – make them out of any 12 contrasting prints that you like; the arcs are long and gentle which makes them easy to sew.
A companion pattern for the Ovals Always cgrKAOVAL Creative Grids Template, but instructions are included for cutting without it as well.  
I have seen this quilt made with many different color combinations.  Pick your favorite and enjoy.
