I have the larger YourStory machine, but my hubby got me the YourStory Photo for Christmas. I decided to give it a try and make a couple of photo books for my mom. It is super easy to use and only takes a few minutes to bind the photos into the albums. These albums I used are the ones that came with the machine. They are 4x6 albums and are a little bit thicker than cardstock.
For the first one, I made an album with some of our pictures from Halloween Day. I used the Lettering Delights SVG Set Zombie Land for the the little zombie on the front. I then used the Ariel font to cut the font out of black vinyl. This album has 20 photos in it. The instructions say these can hold up to 20 pages, but there seems to be more room if you are just putting photos. I think you could probably put close to 30 in if you needed to.
