I've got an order for a pair of voi - veil poi.
You just attach your belly dance veil to the ball and that's it.
I sewed two and two eye-shaped pieces at one side together.
Then I sewed these two together inserting a loop and a cord.
I cut triangles out of the seam allowances and turned the balls inside out.
I filled them with sand and sewed the hole with the whip stitch.
I attached the swivel handles and here it is.
The veil should be just easily knotted to the loop at the bottom.
