I have played around with printing off Instagram photos in the past on 4X6 formats but have never been able to have them come out quite right. This month, I got a coupon from Walgreens for 25% off Instagram prints and discovered they print them in 4X4 format!
I printed so many and love how they turned out!
I used them on this sketch from Sketch N Scrap which featured square photos...
The photos I printed were black & white which worked well with these pretty papers from Authentique.
