Balancing it All cracked me up. My kids (both of them, one boy/one girl) recently went thru a sock monster phase. My daughter went to a birthday party that the mom had made "favors" out of colorful knee high socks. She cut the socks from the opening up to the heel in strips (for a total of 8) and stuffed the toe with stuffing, sewing it shut. The glued eyes on them. Instant octopuses or monsters.
My daughter loved it and the mom sent an extra home with her for her to give her older brother (he was invited to the party, but had a cast on his arm and it was a pool party so decided to stay home).
They immediately went to the "used sock" bag (I keep a grocery bag of worn out socks to use for dusting/cleaning) and stuffed and starting sewing arms, legs on them. Stitching "x"s for eyes, etc.
They are pretty creepy looking and they absolutely LOVED it. Asked me to take them to JoAnn's to pick up some fabric squares and buttons and zippers and stuff to make more (and clothes for them). LOL
My son is 14!
Just make it fun!
