I have been so intrigued with all of the wonderful comments on how to best use my little green half square triangles. I loved the color combinations, but in the end I went with the suggestion Becky made about going backwards in the planning. Find a border print and pull a coordinating color.
I searched through my green fabrics, with not much results. Then I thought about looking through some novelty prints. I finally found something that might work! A green floral with a little bit of pink. I also found more of the dark green, although it is a different pattern, the color matches perfectly. And low and behold, there was a left over 13 x 14" piece with all different herbs.
Here are the HST's shaping into a nice little block.
And here is the first block!
It looks like I have enough HST's to make 4 blocks. I can then add the floral border and use the dark green for the binding.
Yep it's coming along :-) Thanks so much for your wonderful suggestions.
