Hey, thats actually the way i was thinking of redesigning the entire piece, referring to the layered thumb cover. that makes it looks much nicer btw. totally agree with you on the rubbish pattern as well... but its not a bad starting place if you have no idea what you're doing. =P
oddly enough, i had also considered doing a triweave pattern on my hand piece but decided in the end i needed practice tooling so went with the wing design instead.
looks pretty awesome
