I have spent a while working with Project Life pocket pages and wanted to do something a bit different. I took a favourite photo of Toronto and shipped it off to Costo.ca to create a 12 x 12 specialty size photo. The Canadian price is 4.99 and they will have it done by noon the next day after uploading. I usually never give them till noon the next day and run off to pick up my photos with in the hour or first thing in the morning, if I uploaded overnight --- they have always had them done.
Because my photo was formatted for a 4 x 6 ratio, Costco will give you the option to crop your photo to make it square. I decided to use D style pages because of the height of the CN Tower. I didn't want to cut it 3 times that the A page would have required.
While cropping online to fit the 12 x 12 format I tried to keep the CN Tower in the right one third of the photo so that it would fit in the centre of the right pockets. I was quite happy when I started to cut the photo into 4" strips and the tower was fairly centred. 
First I measured the photo to make sure it was exactly 12 x 12 (it was), then I cut 3 vertical strips of 4". The outer two strips were cut in half at 6" making 2- 4 x 6" photos. The Centre strip I cut into 4 - 3 x 4 photos.
Next I rounded my corners and put the puzzle pieces back in the correct order and just popped my photos in the pockets. I was absolutely thrilled with my page and can't wait to try a baby photo.
Things to keep in mind when using a 12 x 12 photo:
1. Most photos will need to be cropped to fit a square.
2. Pick the type of page you want to put your 12 x 12 in.
3. Make sure the style of page fits the type of photo
4. Be mindful of where the cuts on your photo will be. You won't want a cut to go through eyes on a face. Try to keep most of the face within on of the pocket sizes.
