making a mosaic pin

[Bradley Lee]

I want to make a turquoise blue center square --inside a brass tub with black fill in on the outside of square. What size of brass square will fit inside of what size of round tub and where to get them?

I get my tubes and pinns from a place that sells model trains etc.

Look at a hobby shop that sell RC planes and cars they always have a section with different brass tubes and squar stock
