You can find the supplies and accessories to make these Adjustable Rings on my web site:
I have made a little tutorial. These little Rings use very little fabric, so pull out all your saved "scrap" fabric.
Supplies that you need are Pearl cotton 5, tapestry size 20 needles, disappearing ink, scrap fabric, sharp scissors, adjustable ring. (optional is fiberfill cotton, magnet).
Trace the ring pattern using the disappearing ink to the back of the fabric.
Stitch a running stitch 1/3 inch from the ink circle, please pay attention, the starting and ending running stitch start and end on the "front" of the fabric. I use Pearl Cotton 5 because it gives you the strength to pull the running stitch tight after mounting the fabric piece on the ring. After you positioning the fabric on the top, pull the pearl cotton very tight and tie 2 knots, and trim excess fabric.
If you want to use it as pincushion, add the fiberfill cotton. You can also add a strong magnet to hold needles as well.
I have a special kit on my web site for starter, all you need is scrap fabric, supplies are included.
