Sometimes you only have room for a tiny side table or corner table: a stool can be the perfect solution and also give you additional storage space for some small items with this easy modification.
I simply added some shelves that I made from cardboard (from boxes in the recycling bin) that I covered up with some leftover SOLVEIG curtain panel material from IKEA. You could also use contact paper, fabric, wallpaper, whatever you have on hand, to cover up the cardboard. As for the shelf, foam board or 1/8″ thick hardwood panel would also work if you have that on hand. I just wedged the shelves in place but if your shelves are too loose, you can glue them in place with something like “Liquid Nails” or use 3M command strips for something less permanent. I now have the perfectly sized side table and a place for my sewing supplies stored in old cigar boxes. I love DIY transformations like this that I can do with stuff I have around the house!
