I found on old color card from years ago that had little 1" x 2" swatches that are perfect to fill in the tiny little areas that pop up around pockets. They're too small to effectively turn under the edges, so I'm stitching them on flat. I figure they'll be sufficiently stitched through to eliminate them coming away at the edges.
