But i need it!

Someone talk me out of it , quick. I was innocently :) browsing ebay when it jumped out at me, a FULL ROLL of black fabric. Only £40 (or offers), only 5 miles away, it must be an omen. I've no idea what i would use it for, no idea where i would be able to hide it so husband didn't see it, no idea how long it would take me to use it up, BUT I NEED IT!!!! So please, before Debbie the rogue digit does it again, TALK ME OUT OF IT !
