Let’s back up, though. I decided back in the fall that I wanted to sew a Harry Potter quilt for our nine-year-old son. He loves Harry Potter and he’s been using the same red-white-and-blue plaid bedding set since he was a year old, so it was certainly time for an upgrade.
I spent ages browsing online for different Harry Potter fabrics and ended up deciding on 12 different ones. Actually, 10 were official Harry Potter fabrics and two were just fabrics that coordinated: red bricks for Platform 9 3/4, and swirly dark clouds to represent Dementors.
Since a half-yard of fabric is 18” long and 44” wide, this would easily give me 24 quilt squares — two squares cut from each fabric.
Then it was just a matter of deciding how to arrange all 24 squares.
