This is a sampler which I have tried for practicing pistil stitch. The leaves in the middle stem is stitched using pistil stitch.
Regarding the flower I have seen the same in Indus ladies. And I tried that. It has been done using alternate fly stitch and straight stitch. But today I came to know that this flower technique has been done by Leela of www.leelashobbies.blogspot.com. Thanks to her.
