It's called Megatropolis. It's a little difficult to find, but a search on Etsy yielded a few results (here they are if you want to buy some of your own.)
I wanted to keep the pieces large to preserve the unique quality of the fabric. So I just did offset rectangles (8 x 23") paired with 8" squares.
I put 2" strips between the columns
The red polka dot will be the back.
Also newly completed: these Autumn Placemats. I saw a woman walking around the fabric store with the bolt of this fabric tucked under her arm, and stalked her all the way to the cutting table to make sure I got some as well! It's "Autumn Medley" by Martha Negley for Rowan Fabrics, available here.
