This is definitely one of those projects that takes a lot of time but not a lot of concentration. I did it while watching TV last night. The trick to making it look right is folding and rolling the paper different ways.
If you don't have the time or feel like doing it yourself then you can purchase one from me at Salty Sisters for $25:)
