I have a few brush projects in the works. First up is a horse hair 24mm, I have a handle ready to go, I just need to decide which one. A 28mm Super Badger that I'll make a handle for, maybe wood, but I'll have to talk myself into that. A 26mm silver tip grade A with a Russian Olive handle. I'll have to wait until next payday to buy the knot and I'm going to pick up a big Omega boar knot at the same time that I'll make a handle for, probably wood. With a little luck I could be busy on the 4th.
Kudos to you for trying this. You have more energy than I do! I'm afraid that I'd find it too easy to click on the internet and purchase a new brush.
