Like I said, I went to that store today and too my time browsing their inventory. It was well stocked and to be honest I could not buy half the things I wanted but I still did not leave empty handed and made some notes for the future investments - a monocle or magnifying glass for a starters. The reason why?
Well, here you can see the gold links I used to make the previous ring compared to the golden and copper ones I bought today with a coin and a nail clipper to get an idea for the dimensions we are talking about.
I made another ring out of them as you can see, using both the copper and gold but my eyes are very tired and hurting like hell. I won't be trying something that small for a while.
I apologise for the poor quality of the photos - but I can barely see right now.
