I like the option of hooking things on to wire sheves too. If a surface is needed for containers you just put something flat onto the wire part.
This craft cabinet thing has a good variety of shelf depths for various supplies. I wouldn’t want the fold up version but I like the organization.
Even though I can be quite messy, I find chaos upsetting so further down that thread is a photo of my shelves with baskets on them. I hide the mess in a consistent looking front. I have Kallax cubes in the sewing room too, they are great for so many things. If I find time this summer I’ll finish reassembling that room & take photos.
