Having a box of mismatched or old socks is not the most exciting thing in the world. Wondering what to do with them once your kids are too old for sock puppets is time consuming and not fun. However, you may now relax because I have a bunch of uses for those old things. Take a look.
Use a clean fuzzy sock over a water bottle or large covered cup with a straw to keep it from sweating on wooden furniture as you take it from room to room in the summer.
Put some baby socks on the legs of chairs to keep them from scuffing hardwood floors.
Use the leg portion of old clean socks to protect the sleeves of baby clothing. Bibs are great for the front of the shirt but with 'learners' even the sleeves get dirty.
Can you add to the list? Have a great day!
Meanwhile .... keep it simple and make it real.
