Three employees of the Mittagong wall and flooring store have taken up the challenge and grown out their moustaches for a good cause this November.

Franchisee Adan Traynor said it was fun but had a serious tone to it as well.

"We have raised a whisker over $500," Mr Traynor said.

"The Amber network has raised just more than $7000."

The gentlemen have enjoyed their participation and for Mr Traynor, who has never had a moustache, it has been especially fun.

"It's a big change but it has been effective," he said.

"It's been a lot of fun with our regular customers.

"The whole experience is a practical call to attention."

The gentlemen aim to reach the $1000 by the end of month and have stressed that every dollar counts.
