My friend Carolyn really liked the flowers I've been making, and she bought two for her niece. So I thought I'd make some more. And I came up with a pattern for making leaves:
This flower is about 3" across.
For the leaf, I did a chain stitch the length of the leaf, and then did gradually increasing/decreasing stitches along one side, and then back down the other side. This gives it the look of a real leaf, I think.
It's a cute little flower. The middle color is a big more beige than this photo indicates.
