I'm pretty sure "Meow meow meow" means "hi there".
At least, on this card it does! I made this for my youngest when she went to sleep-away camp earlier this summer. The cat looks like our Cristabel! I placed the kitty in a summery scene, made with die cuts and a border punch that looks like grass, if you squint your eyes and let them go all out of focus. ;-)
I used a new-to-me Papertrey Ink Mat Stack 3 die, cut it in two pieces, and reassembled so that it appears longer than it really is.
The "meow" sentiment from Cat's Meow / PTI appears all over the white die cut, but also in a subtle way on the blue card base.
I used a white craft ink (Crystal, by Ranger) instead of Versamark, to heat-emboss Kitty. Didn't work out as expected. Should've used juicy Versamark, and gotten a better image. This version just makes Kitty look dirty. White Opal Liquid Pearls stand in for the eyes.
Our daughter loved the card, and loved receiving happy mail at camp.
