Aspect ratios are calculated by dividing the internal diameter of the ring by the thickness of the wire
For most (all?) chain maille projects, the aspect ratio is vital
Too big, and the weave is too loose. Too small and you can create a chain that doesn't bend!
This may seem like an obvious thing to say, but always use the same units in all boxes. i.e. use all inches (decimals - so half an inch is 0.5) or MM
We know there are hundreds of these out there, but thought we should add this for completeness
Especially as we know so many other places buy their rings in from America or Canada.
We have also noticed that most American chain maille patterns are in inches, so this should help
When converting inches to MM, please fill in the three boxes - the first is the whole number, the other two are the top and bottom parts of the fraction
