I was pulling out more homespun woven plaid fabrics to make my trees when I spotted the one I used in this block. It seemed to want to coordinate with a red, so I picked that one out pretty quickly.
There is some green in this fabric too, but since I just did a block that is essentially red and green (though more muted shades of each), I decided to try out a brown instead. I like the combination, and the taupe/beige print near the center. The brown print also pulls those two colors together, and all three (well, four when you consider the plaid) prints contrast in a pleasing manner. That brings the number of blocks so far to 14, I think.
