I don't know where it came from, but I would point out that it would not be legal for another digitiser to copy the design. However, you could combine other designs to get a similar effect.
Well, if I could just get close with the font, but I'm having a hard time finding one and I already have the hand(s) and heart... My designs are so disorganized. :(
It is adorable, but I don't know where it came from, sorry.
