Well, I called my own bluff and ordered some horn from Vietnam. I ordered it last Wed morning and received it just now. It looks good but I don't know anything about horn. It's all cut .4"(1cm) thick and 1 3/4"(4cm) wide. The longest is 31" and shortest is 27". It thins out toward the base of the horn. How thin can the thinnest part be when I'm cutting the finished pieces?
