This collection is new in the shop, and it is just lovely. There's a nice blend of crisp blues, yellows, greens, reds, and oranges -- my favorite is probably the houndstooth. You can find all 18 prints in the shop.
The folks at Riley Blake also created this very pretty churndash pattern to highlight the Avignon collection. Again -- churndashes -- my favorite! The pattern is free, and you can download your own copy here.
