We've just had one of our occasional postcard swaps on Bubbly Funk though (the forum has moved!). We took inspiration from autumn this time and I made a card for Nicky.

I added a bit of "texture" with a crackle stamp and that was it - completely flat for "naked" posting.
Nicky says the PO franked both sides - sigh. We've had very few mishaps with our postcards so I guess we should expect the odd one every now and again!

I got Dina Kowal's Borderless Watercolouring tutorial a while back and that inspired me to have a go (although obviously I didn't watercolour). It's a nicely presented, photo-rich tutorial if you're looking for a good guide from somebody who knows her colouring onions!
