Here are two more sets of finished ATCs - these are ones where I was th third person to add something, so I didn't have to worry about leaving space. The oriental card spoke to me straight away - I knew it had to have some of the little Japanese squares. A gold foil flower finished it off.
The seahorse definitely needed something at the bottom of the card, so I cut a fun green tonal paper into freehand seaweed. I think it works!
