Paper Source uses this font often and I'm curious of what it is and if it is available anywhere... I love it. (it's the font on the card that I am curious about.)

(x) Script font from Paper Source - lettering by Crystal Kluge {Christian R, Trish}
It looks like custom lettering to me.
If it didn't read 'Thark You' it would be quite good.

It's hand-lettering by Crystal Kluge.
