Thanks for the vote of confidence. I used an ammonia hardening technique I learned from the local tandy guy. 1 part *NON SUDDZING*ammonia to 6 parts warm water. the longer/more times you soak the harder (and more brittle) it gets. Very little shrinkage and doesn't get soft in warm weather.
Two 2 piece domes, laminated, one inside the other, no structural metal.
The aventail, shikoro in Japanese, is tied very tight in the pictures, I left the laces long so the owner could adjust it to his preferences.
Looked at your website. Very nice work, you have inspired me Sir, thank you. Here's a link to mine, such as it is~ http://corviileather.uphero.com/
I play mostly in the SCA, but intend on looking into the local RF here in CO.
I think the SCA may be a viable market for you. I've been to a few good sized events in your area. http://www.sca.org/
Thanks again
