Even if the stringing isn’t going that well, there’s plenty of popcorn to eat.
This activity is highly self-explanatory, but here are a couple of tips:
Look for plastic darning needles at the craft store. You want one that’s pretty pointy, but plastic is safer.
Once the kernels cool off they start to get a little tougher. If it gets too difficult, try a fresh batch.
Use a single strand of thread to prevent snarls. Button thread works well, and is thicker than regular sewing thread. Little hands will manage it better.
Start each strand with a button or a popcorn kernel tied to the end of the thread. If you just knot the thread it’s likely to pull through.
Keep the strands short, to match young attention spans.
Last, but not least, don’t set your heart on finished strings of photo worthy popcorn. My kid are his off the thread. This is very much a “process not the product” activity!
