I’ve spent some time looking around the Net for doll makers and some of them are pretty impressive.
However, there aren’t any specific makers for Sanrio characters. The best I’ve come up with is a place called “Dollzbliss” and they have a kitty section that’s quite nice.
If you have your own imaging program (paint shop pro or photo impact), you can capture the image of your doll within the building area using the Print Screen button on your keyboard; then Paste as New image into your imaging program.
This will allow you to make easy modifications to your doll including cropping, re-colorizing, and adding your own text & backgrounds.
Here is a very basic kitty doll I just made:
If you know how to animate a .gif, then the possibilities are endless and you can “kittify” your blogs & webpages to your heart’s content.
Here’s the URL for the online doll-maker:

Hope you have fun with it and when you’re done show me what you made!
