I guessed on a couple of the prices, but they should be very close (I've been keeping this list since I started buying materials). I guess on all of the time. I know I spent 16 hours the day before I needed it done (I spent 8, my mom spent 8. I figured if I'd been doing it all, it would've been 16 hours), and I calculated how long the corset took by how long it took me per yellow swirly thing. Ouch....no wonder I haven't slept much in the past 5 or 6 weeks.
But yeah! Lots of time, and quite a bit of money. Even after looking at that, I think it was well worth it. :D
