I constructed a flower-pin tutorial last fall, only to discover that my photos were too low-resolution (I still don't know why...) I love this project and will try it again with a higher resolution!
First: find a sweater to shrink. This one is cashmere, thrift-shop purchase for $1. Cut "rick-rack." (It doesn't have to be exact.)
See? Imagine a pansy.
Sew a loose running stitch (it's yellow so you can see it better, not because I can't match, silly)
Pull the running stitch tight while rolling up the "rick-rack" you made.
Sew right through the whole "bud," close to the bottom.
Shape it-- coax it into a pansy shape.
Add a few heavy-duty stitches to secure the whole thing together. Then add a bobby pin and a leaf.
And some yellow beads.
More realistic when pinned to a child's hair.
Roses are next:
