All coins I've used had pre-drilled holes.

The gold coins were pretty standard, I've seen them around a lot. The copper coins are Harry Saroyan coins.

Once I've established my "base" I start with the top row.

I use several layers of waxed Silamide thread. Waxed for extra durability, Silamide for extra durability, several layers for extra durability! I also knot each coin individually, for extra durability!

The key is to not sew them onto the base TOO tight b/c you still want them to hang freely. The next row is placed between each of the coins above it, about 3/4 below the row above, so that you do not see where these are sewn.

For the top row I would often incorporate a bead or sequin in the several layers of Silamide thread, to hide the thread.

If anyone's interested, I can post extreme close ups of my work.
Anybody else who has other techniques or suggestions would be cool to see how they do it, too, for everyone's information.
