It was supposed to look like honeycomb. It looks like cheese. Just another example of how a very subtle change in color can make you think one thing instead of another.
Anyway, this was from a pattern dictionary in crochet. In can be made in just about any size and I associate it most with a granny square. There are lots of chain gaps which are then filled up on the next row with double crochets. Grab a dictionary and search out a similar pattern. They make for good practice in crochet basics.
