Just bought a sensory rail from tts. Any ideas what to put on it for 11 month old?

Wooden Spoons
Bells
Ribbons
A string of giant beads

I have one of those! Today mine has several lengths of ribbon, a voile-type scarf, a shower puff thing, a crocheted scarf with tassles and a set of metal measuring spoons

Thankyou for your ideas. Will try some tomorrow.
