This means you add one finger size to the length per millimeter
For example a piece of material 1 millimeter thick, to make a size 9
ring would, measure a size 10 on the ruler. You add one size per
Another example, 1.5 mm material would be for a size 9 ring, would
measure 10.5 on the ruler. You simply cut out that length and make
It is the quickest way to make a band ring I know.
Any metal works, it’s the thickness that you need to know.
