I've had this backpack template long time ago and just got to play with it recently for a Graphic 45 project. It was fun assembling, I made three! Each one for my nieces (Cheska, Chanelle and Chloe).
I used my favorite flower die at the moment, the Sizzix tattered floral die. You might probably see projects from me with flowers made out of this die for a very long time hahaha I also used this to my Mother Goose tag mini-album.
I also made coordinating mini-albums to store those back-to-school photos of your precious little ones.
