While working on a netted bangle with Duos, I ran out of beads at the halfway mark.

I wasn’t ready to stop so I started a new one using Twin beads.  The original is six Duos around, the matte blue and alabaster bangle is five Twins.  The main difference I have noticed is the Twin version is much more wibbly-wobbly.  While still very pretty, the gaps between the twins are larger and it does not hold its shape as well as the Duos.
