I finished Pillow # 1. The design is not difficult to stitch, pretty fast. To fill the background - this is a boring part, but, well, it's done. It was stitched on 40 count silk gauze with DMC floss. You can use any colors while stitching this pattern. You can make a pillow, a chair cover, a footstool (probably using the smaller count of silk gauze).
Just an example
