How about an ice cream sundae?
Think of the brown floral as chocolate. Of course, with that green in there, it would have to be chocolate-covered olives or something ... No, just chase that image right out of your head.
Anyway, if I think of the brown floral as chocolate, then the light floral might be vanilla with, you know, those rainbow sprinkles on it.
Is this image working for you?
Since the color in the light print gets kind of lost, I want to use patchwork to extend the theme of lots of colors on a vanilla background. With a little more rummaging in my stash, I find a latte-colored monochrome floral. The print has that same I-came-from-a-haunted-Victorian-mansion style as the other 2 fabrics. Perfect.
It also has the same drabness that plagues the other two. Maybe mixing in lots of color will liven it up. One can always hope.
With a sigh worthy of Jane Eyre, I cut 400 3-inch squares (40 for each of the 20 blocks I'm making), and slice the squares diagonally to yield 800 half-square triangles. Now I need an assortment of reds, blues, greens, and purples to make another 800 triangles to pair with them.
To be continued ....
