Not a single nail hole involved! For the Menu Board and Dry Erase Board, I used the "Command Saw-Tooth Picture Hanger". This size will hold up to 5lbs!
For the Chore Charts, I used the "3M Command Picture Hanging Strips". Seriously, these suckers are awesome and I use them all over the house ...
You can find these at just about any shopping center like Target or Walmart ... even home improvements like Lowes or Home Depot.
I hope this helps you get one step closer to creating a Command Center for your home ... happy shopping!
