in the end, i came up with my own "KEEP CALM AND PIN ON"
and besides buttons to give away, I'm also giving away "MUSTACHE" pins too!!! plus i managed to find this cute phrase online.
"MUST pin now. STACHE later." which uses the MUSTACHE word!
here are the print outs and we've stuck them onto vanguard sheets.
hubs cutting the first few to try out.
next we have to puncture 2 holes to fit the back of the pins.
this is how the final product looks! Here's the Front
and here's the back!
