Crafty creatives.. my own project

My purse is very large, due to the fact that I have a LOT of cards. So, to make my handbag a little lighter, I've decided to make a specific purse, just for cards.
I've been using the fabric from my Crafty Creatives box 1
This is what I've got so far:

Some of the pieces for the cards to slot into

After the first piece was stitched to the basic lining

And the second piece

Each "page" of the wallet will have space for 3 cards
I'm still trying to work out how I will tidy the edges of this, but I have an idea. I'll have to try it with pins first!
