I meant to post this a BILLION YEARS AGO, but I only just now got the pictures. This is the corest I made for Halloween. I made it out of duct tape, the boning is hanging file folder pieces, and I splurged and paid for a real busk. I also got all fancy and put in grommets, which was a pain in the ass, but hey, it looks better that way!
It has a two inch reduction and I managed to get it almost all the way closed. I used flourescent orange, black, and chrome duct tape. (The chrome is like the regular silver except SUPER shiny. The pictures don't do it justice at all.) And a teeeeeeeensy bit of red for the spider's eyes, but it doesn't show up in the pictures.
