I used my copics and some Stickles to colour up the stamp, and I also made the umbrella 3D! I simply raised the bottom of the umbrella on 3D foam dots, and used flat adhesive to stick the top of the umbrella down. I also coloured the edges of the image underneath so it almost looks like you can see the other side of the umbrella!
Here's another angle of the umbrella:
I didn't realise but this doesn't give a good photo of how the tip of the umbrella is actually flat with the rest of the card - the umbrella looks like it flairs just like a real one. I've left the sentiment blank for now (you do get several with this set though), that way I can chose the occasion at a later date.
