Yes I'm a Project Life addict. I'm more of the 'I have lots of different kits that I mix and match' than the 'use one kit for a layout, month or year' type so I have colour sorted all my core kit cards and some of my mini kit cards. Although I haven't colour sorted all my cards and kits as I still need some sorted according to theme such as school, Christmas, Valentines, travel etc.
Sometime I simply flick through all my cards to find what I want according to colour which I love to do but this can sometimes be a little time sucking!! I also often have people ask what kit certain cards come from or I want to find a co-ordinating card from a certain kit so I made a reference guide up.
It's a handy 6x4 size and bound with a simple ring for easy flicking. The cards were created using the Digital Project Life Card Design Reference PDFs available here. Unfortunately not all kits are displayed but enough to be helpful and hopefully they'll release more at a later date (I'm crossing my fingers).
I simply downloaded the PDF and printed them on to the Becky Higgins Project Life 6x4 white cards. I fed them in reverse side (smoother side) to get a better print. I use my Epson Picturemate but you could do this on any printer. I'm also a Studio Calico subscriber so I also printed out photos of the monthly kits onto cards too.
A simple hole punch in each corner and a Kaisercraft ring binds them all together.
The simple cover that I designed is available for downloading here.
I did the same printing onto a 6x4 white card but I specifically choose borderless printing for the cover.
