What can I crochet with 3 balls of cotton?

[TheGherkin]

It’s multicoloured. 4 ply (ish). 50g balls.
Need a little something to keep me busy on a plane and my blankets are too big.

Tablemats or washcloths? Something like this

wash cloths, face cleansing pads, little baby vest, little summer scarf/ shawl using big crochet hook?

Key rings, little toys?
