I love Instagram more than Coffee... ok, that went too far :)
I'm a project lifer and love to scrapbook, and I use instagram for lot's of photos and love to add them to my weekly spreads. I use quite a bit of different sites and apps to order my instagram prints.
FYI, you don't have to be a scrapbooker to print your instagram prints.
Snapfish --> it's my number one site. I got there for mostly all of my prints. They have the best quality hands down.
To order an instragram print --> make a collage with either 2 instagram prints on a 5X7 which gives you to 4X4 squares.
Or, add 4 instagram prints to a 4X6 and it gives you 4 2X2 prints. I just cut them out.
Persnickety Prints.com --> They have so many different sizes of prints.
I have ordered, 6X12, 4X4, 2X2, 4X6, 8X10
Great quality and shipped right to your house.
Postal Pix -->
Great app, you can order them right from your phone, pay with paypal and they are shipped to your door.
