I'm not crazy about olive green, but if you add orange to the green/yellow combination, you have a winner.

Olive green is probably my least favorite color.

Ugliest? A nine patch. Someone else's blocks in pastels with dark striped fabric fours. I set it with a pale turquoise polyester blend. WHAT was I thinking?
After that I realized: Life is too short to waste on ugly quilts.

I love mustard and olive (in color more than in the jar).
