I found the pattern for this pincushion, called wildflower-pincushion here.. I made a sunflower pincushion with this pattern.
So, for explanations and pattern please cf to the website above... I will show you only some pics how I sewed it. I sewed the little petals before cutting them out, I think it's easier to do.....
the same for this pieces, as you can see I sewed one seam before cutting them out...
