Blue Flow

I want blue gloves for The Wave on Saturday. Where can I get them? Sainsburys only have washing-up gloves in yellow, green or pink. Woolly or blue-nitrile gloves would be fine too... I suppose woolly would be best as my hands would be simultaneously warm and blue. Ideas welcome. Has to be well under a fiver though.

Place bets now on whether I'll manage to learn the Splashdance in time!
