@ Wiredkitty: i will try target, since i need a shirt from there as well. i didn't think they'd be likely to have yellow since it's not a color i've seen before, but occasionally they have something off-beat. (like my pretty blue socks - it's a blue i don't think i've seen in any clothing before; now i can't match it!)
@ Immortalbeloved: i'd prefer not to try that again, since i tried yellow dye on sock knit for a wristband, too and it came out orange. obviously i had it in too long. i've never gotten dye to work quite like i want it to. =P but thank you.
@ Pocketfightr: in the first post, i stated that i already looked at sock dreams. sorry. but they are great. there's a pair i want, not for cosplay. =)
@all: i have the matching green fabric already, since it makes up the bulk of the costume. i believe i will sew it on. thanks.
