Basically, all you have to do is dedicate at least an hour a day to making clothes for your DC (or other people's DC) next week.
All the info is here.
I'm quite excited, but could do with some moral support from other MNers who would like to join in! I can't imagine I will make much in 7 hours, so will probably be putting in more hours than that 
I think I will also write a tutorial on making shorts for kids and post it on my blog on the monday.
