Using 1.5mm or 1/16inch, have machine auto measure your wood. If you want earrings copy and paste the design to make 2 sets, for a single necklace keep the file as is.  Then hit start. Paint as I have or make your own style. I suggest painting separately the frame from the back, then use glue and clamps to attach. I use a clear glue so it does not show when dry.
