What are chenille steams?

I believe you mean chenille stems. They are essentially pipe cleaners, but are sold in craft departments, and are longer and sometimes available in colors.

Yes they are pipe cleaners. You can also find them in $ and school supply stores and departments.

Pipe cleaners! That make for great craft projects!!

Theyr'e like a thicker pipe cleaner- They're loads of fun!!

good for cleaning things like pipes or faucets, fun ties on bread bags, chip bags. Tie up tomato or vining plants. Stick in styrofoam creations as feet. Fun rings or crowns for little girls. Endless possibilities.
