Kilt pin project questions

[ChromeScholar]

First, if those are wet stains on the leather, from a leaky flask cap, I'd not want the liquid staining the kilt.

They're not.

Second, 2 ounces when full sounds a bit light,

Weighed it on three different scales, the heaviest it weighed was a little over two ounces.

I'm not convinced it would make a good pin. Sorry.

No need to be sorry. I asked for your opinion, I'm likely still going to try it.
