This is a simple craft meant to help fine motor skills. We made cereal necklaces with twine and half of a pipe cleaner.
I cut a pipe cleaner in half and twisted it around the end of the twine to make a ‘needle.’ The needle made it easier to thread, and I used it as the latch when we finished the necklaces. This kept me from needing to tie it and possibly creating a strangulation hazard (I may worry a bit much about those, but who ever regrets being careful?)
My son loved making them too but ate them one by one as he got them on the strand. At least he got fine motor skill practice in ;)
