Brother Vic,
Sorry I can't help you more Brother,ever since I had 660 volts go through my arms and shoot out the top of my head.....I've developed "stupid fingers & dumb thumbs" I haven't really been able to craft anything in years.
I can offer you an opinion though.....
Back in the 1700's the Eastern Indians traded heavily with the French and English traders.One of the "goods" very much in demand were Colonial shirts. I'm sure you can find patterns for these and I'm sure they could be easily hand sewn.
I will also add.....Let your spirit be your guide.....If you like it,wear it!!!!! If you feel that "it" makes you look good.....It will!!!!!
A Colonial shirt,breechcloth,leggins,and moccasins,is about as "Native American" as you can get!!!!!
Take Care My Brother!!!!!
