I wanted to come up with a new version of my stitched neck choker that was flexible and didn't incorporate any metal findings (since I've had requests for that in the past). While some tests didn't work, I figured out I could create stitch “beads” and put them on an elastic base and this worked out very well.

Created using Tinkercad with basic shapes.
