Chenille Stems
The wire down the middle is what lets these hold a bend, and it is also the thing to watch: once cut, the end is a sharp point, so younger classes want them used at full length or trimmed by an adult. Thicker stems hold structure for models; thin ones twist into detail. Buy bulk packs by colour rather than assorted if the activity is planned. See pom poms, foam shapes and school craft supplies.
