8x8 Cards

Well I thought I'd have a go at making one of these and it's turned out quite well. Only problem is, I forgot that I'd need a big envelope to put it in. Does anyone know where I could get a template for one. I've got A3 paper but don't think that's going to be big enough,so will probably have to join it somewhere.

Thanks

what card did u use for an 8x8 card?

I use 2 sheets of A4 card for the card. I got the instructions on a blog but can't remember which one.
