Over the last few years I have collected tons of journaling cards in 3x4 and 4x6 sizes. I had them all lined up in an Ikea cart, but it was an unorganized mess. I LOVE this cabinet filing system! Three drawers for 3x4 cards and 2 for 4x6 cards. It includes tabbed dividers so you can sort by manufacturer or theme or whatever makes sense to you! It is sturdy construction, but not overly large (I was running out of space in my craft room so I didn't want anything enormous.) I was able to fit ALL the cards I had collected in one cabinet with some space remaining for new purchases! I especially love the book plate detail on the drawers.
This is such a great little cabinet! It does hold my 4X6 and 3X4 project life cards but I don't do project life exclusively so I use the other drawers for other supplies - and honestly, this combined with the sleeve shelves is the greatest idea! It looks very nice on the desk, and is SO usable for whatever you want!
