I've used the Art Impression stamp Happy Purr-thday.
For my spots I used some polka dot patterned paper as "wallpaper" pretending the kitties are looking out a window.
The sentiment from the stampset I found too small, so I used a Simon Says Stamp sentiment from the set Furry kisses 3x4, the little paw also from there.
I've colored the beasts with Spectrum Noir alcohol markers.
I've used some wood patterned paper as the window frame.
then I wanted to put some flooring down to anchor the cats and first cut some stone patterned paper, but that wasn't in proportion to the cats, so I grabbed a marker and just colored some shadows in..now that was rather stupid cos it bled right through the front panel....so I cut another panel to cover that....
you can see it in the video, big ooops ;-) that's why I reached for pebbled paper, duh...silly me..
