I tried the 100 Day Project last year and got a couple dozen days altogether (and made a layout about it).
This year I got a little 4x4 book to fill with whatever few minutes of craftiness I come up with. But the book only has 80 pages, so it's a 4/5ths 100 Day Project.
It has a little water coloring, a few mini scrapbook-y type pages, and a lot of color. It'd be really cool if I could actually get it filled...
