Anything you want. Art supplies, magazines, yarn....
I use mine for lots of things...under my coffee table: magazines, I hv one large one my grandkids go to everytime they come over, it’s filled with art supplies, coloring/activity books, sm. canvas for painting markers etc. if you’re looking for a decorative piece you could always look up a diy then go to the dollar store n make something or take to a local florist n they will make you something...baskets are great gifts...if someone’s not feeling well, fill with puzzle books, homemade or canned soups a card, or a basket for any gift occasion...They are as versatile as mason jars in that they can be used n utilized for so many things...have fun!
