I have made these recently with 6 of the grandkids and they were a hit. Hailey helped me prepare the strings. To do so you just have to dip the ends of a length of yarn ( It needs to be long enough to slip over a child's head easily when the ends are tied together.) in wax about 2-4 in. (I melt old crayons in a rinsed out can set in a pie pan of water on the stove. Caution: Don't turn the heat up high to avoid fires. When wax is cooled on a paper towel, the melted wax makes a sort of needle suitable for threading through macaroni, rigatoni or similar material. (Hint: To dye dry pasta, place in large zip-lock bag with food coloring and a couple T. of alcohol. Close bag and shake. This results in brighter colors.) Dry pasta on paper towels.
This is a great activity to increase fine motor skills.
Two-year-old Jacob called it a caterpillar so you may have to change the name for boys. Because we did this for our 100's Celebration in kindergarten, we put 100 fruit loops on the necklace in groups of ten, changing the color every 10 fruit loops.
Children can eat the cereal off the necklace for a snack when desired. This makes a good snack for hiking on a trail.
