I think a block that size is attractive - especially on a sampler and with sashing in between. I personally like a block that finishes 6" so that all it's components are super easy to calculate - like this Charming Instant Block quilt.
All blocks are 6" finished, with 1" sashing in between, separated by rows of 5" charm squares. This quilt is from a class I taught at my guild meeting to make multiple blocks at the same time using Eleanor Burns and Billie Lauder's quick methods. A few strips, a few squares, a few stitches, and voila! Instant blocks, Instant success. We had 12 sewers, plus 12 people pinning and pressing. We sewed for 1-1/2 hours, and made 174 6-1/2" blocks to use for charity quilts. Patterns available :D
