yeah that was the only site i found with any guides on a pretty quick search. that being said, there's a lot that i'm going to change in any subsequent designs. there's really too many unnecessary pieces that make it stiff and somewhat complicated. in addition, if you don't use the right arc length for the ovalaid pieces they tend to wrinkle up near the rivet in the middle. it looks fine but i'm planning on refining it and going to an overlapping panel type gauntlet. i also made the hand part a little too small, but again, it was basically a first try at anything like this. i only started doing leatherwork a few weeks ago. =) As far as the thumb design goes, it really only covers to the knuckle, because the gauntlet overlaps a little when you make a fist so you're still covered. I'm considering doing a fingered glove type guantlet for my next armor piece, or possibly a shoulder/arm piece. its either that or a helm. =)
the cuff was also a not quite what i was going for so i attached it to a pretty basic bracelet that i stitched to some basic bracers i made.
i'll cite any resources for patterns i use in the future =P
