Beadsmith has made a One Step Looper that will make three sizes of basic loops: 1.5mm, 2.25mm, and 3mm. With no measuring or cutting, the exact same size loop will be achieved each time the tool is used. It accommodates 26 gauge all the way up to 18 gauge. The 1.5mm Looper was used here with 10mm faux pearl.
Slide a bead on a head pin. There is a hole in the side of the right jaw of the Looper for the head pin to pass through. Press the bead against the edge of the left plier Looper.
