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.
