Anyone know where I can buy this kind of black board or anyone doing this?

I actually enjoy DIY & my fave spot for materials are Daiso, IKEA & Spotlight. Be creative & have fun creating a one of a kind Happy Birthday Notice for your precious child

I like the selection on lazada SG - http://www.lazada.sg/rorychen-chalkboard-wall-stickers-with-chalk-intl-4384027.html

Ikea, Spotlight and Art Friend does! If you're looking for a smaller version, think Daiso has it.

You can get these at IKEA, Spotlight. Think Popular or Daiso have a smaller version.

Ikea sells them! :) http://www.ikea.com/sg/en/catalog/products/30167852/
