This is actually a pattern for a cute little bag, but you can turn any square motif into a larger block by adding more rounds. The pattern link is a direct download of the Japanese pattern. It isn't in English at all, but the chart is easy to follow. A reference photo can be found on the Ravelry page for this pattern.
We had another stay-home snow day today. It was nice, but I can't wait for it not to be cold anymore!
