I have 8 ft tall shlef/cabinet units from IKEA. They fit the square tubs and have some drawers, which are super helpful for organizing all of my sewing, costuming, and paper crafting supplies. Clear bins with lids are another must for me, so I can see at a glance what I'm looking for.
IKEA Kallax all the way and Your Way Cubes from Thirty-One. I have 2 Kallax units in my craft room. A 4x2 and a 4x4 with the desk. They are super popular for a reason. I can store of my scrapbook paper, vinyl, my hear press, fabric and pretty much everything I use in my Your Way Cubes and Fold N Files which fit perfectly inside the shelves. You can store your die cut machines on top. I’m also going to tag you on another cart I bought for my machines.
