I have added a booklet layout in the available PDFs for 10 Downing, for both A4 and US paper sizes.

The booklet layout makes it easier to print and have the pages all in the correct order when collating and binding. The existing spreads and singles aren't going anywhere, so this is an additional download option. I intend to do this for all of my projects that are more than just a two-sided pamphlet (i.e. Kiwi Acres and Tiny Titans), so keep an eye out for those updates soon!
