Book shipping date scheduled
I've heard from Make That Thing - the books are now being printed, and are scheduled for shipment from the printer to Make That Thing on 9 August. They're being printed in the USA, so that delivery should be fairly quick, and then Make That Thing will begin the job of packing and sending copies to all backers! So I expect you will start receiving your backer copies around mid-to-late August. (It's a little bit later than I anticipated when I started the Kickstarter. I'll know better next time!)
The postcards are also being printed now, and should also be ready by the same date.
I'm going to see about getting my hands on the PDF version sooner, so hopefully that will be available in the not-too-distant future as well.
