Help: Looking for elastic for beads

[Beulah]

I'm trying to find some string-like elastic to make bead necklaces / bracelets.

Have plenty of beads and can find plenty of thick elastic for clothes.

Does anyone know where I can definitely buy some of the thin stuff in East Dulwich / Peckham?

Thanks.

Really Maria on Lordship Lane near Bishop pub. I got some very very thin elastic there recently.

Many thanks
