Just inside the door, I set up 2 IKEA tables in a small nook that isn't too visible. I had my husband hang three large hooks for my 3 biggest kids' backpacks. I have the tables just under the backpacks, supporting the weight because my kids' bags weigh a lot! My 2 youngest slip theirs under the tables.
