It's wonderful to have all sorts of jewelry making resources on the internet. Less wonderful is the non-standard way of expressing jewelry wire dimensions. I'm still on gauge but others use metric and imperial measurements. So a fine applause to House of Gems infographic or chart on all things wire. Click on the link to get the full chart.
I found the first part of the chart so useful as it is so annoying to have to convert units. Yes, even with a handy app!
The rest of the chart covers shape, harness and the different types of metal used with their relative uses and benefits.
