Simple ring band for single bead placement

Make a flat band/strip of clay 1” longer than desired length, embellish or texturise as desired.
Use a cocktail stick or sharp tool to make a hole at either end (or drill once fired)
Shape the band to size on a mandrel, curve out the excess ends leaving a gap in the centre to fix the bead via a rivet
Once fired, place the bead into the space using wire and create a rivet to hold in place
