Here’s how I did them:
Next: Pin one of your white circles to a green circle, centering it in the middle. Then, using your white thread, sew little lines like so, attaching the white circle, and making it look kiwi-ish.
Then, grab your black thread and start your seeds. AKA french knots. Here is a great tutorial for french knots. Continue around your white circle. It’s really not that hard once you get the hang of the knots!
Next, pin your circle in half, and using your green thread, start sewing a blanket stitch around the opening. Here’s a good tutorial for that stitch. I would try and show you myself…but these are so good. (and already done!)
Do the blanket stitch 3/4 around, and then stuff a small bit of poly fil into the kiwi slice. Not too much, just enough to give it a little shape. Continue stitching and finish the ends off however you normally do that sort of thing.
