Here’s a really nice tutorial that shows how to fold different shapes of petals: http://kurokami-kanzashi.deviantart.com/art/Kanzashi-Tutorial-Part-2-43068363

I cut 10 red cotton squares for the petals, and 6 larger green cotton squares for the leaves.

I folded each petal and glued the bottom edge to itself with a tiny bit of fabric glue to keep it together, then when the glue was dry I ran sewing thread through near the middle of each petal to join them together and formed them into a circle. I repeated the whole thing until I had two circles of 5 petals and one of 6 leaves, Then I stacked the three circles (with the petals and leaves offset) and sewed them together with little stitches that don’t show from the top.

Finally, I made a circle of 6 yellow beads with one in the middle of the circle, and attached it to the centre of the flower.

After that you just have to tidy up the reverse side and add a piece of backing fabric with a pin attached, or whatever else you’d like to do with it!

I hope that’s enough to get you started! It is a bit fiddly, but it’s a lot of fun to make
