I have one in my closet. It houses some photo boxes with different things. Tags, envelopes, finished cards in categories. Wedding/ congrats, Holidays/get well etc. Some embellishments, alphas. I still need to reorganize it.
Mine have my albums, baskets of dies, stickers and alphas, decorative boxes of embossing folders, 3 ring binders full of dies and stencils broken down by seasons and several decorative items I've made or gotten in swaps I used to do.
I have the 5x5 kallax. The bottom has kits, the 2nd row has my paper pads, the 3rd one has card stock, vinyl, and specialty papers, the 4th one has drawers with tools, cards, blanks, sewing supplies. The top one has some albums, the Creative Memories photo boxes, a couple more of clear 12x12 organizers drawers from Micheal’s.
