Instagram is all the craze these days and these and it's so fun to have those memories up on the wall! This set comes with 20 collages but the awesome thing is this set also doubles as a 12x12 300ppi album template which includes 20 layouts and a custom cover!
I used WHCC guides, but they will work with most labs (just make sure to check their guides before printing). The templates were made in CS5 and require some knowledge of layers and can be used in Elements, Photoshop and CS versions of Photoshop. They are .psd files so you can change colors & edit text to suit your needs.
For extra help using layers, you can find a quick "how to" video on my Facebook fan page
