I don't eat seafood and have never tried tinned sardines. But when it was requested as a pattern, I thought... Why not? Sardines and tins of sardines are certainly having their moment in the sun at the moment! So here's a cute foundation pieced version, and it includes space to add some text or fussycutting on the label to make the tin extra cute. 

Both versions of this foundation paper pieced pattern comes in a range of sizes: 5", 6", 8" and 10" square.
