This is a question I find asked incredibly often by those who are either in search of an image of a hard-to-find deity or just don’t have the money (sometimes the two aren’t mutually exclusive. I’ve seen statues of hard-to-find deities that are quite pricey). Luckily there are very simple solutions to this problem that mostly depends on what you want to do with the image.
Print off an image. If you really want to get creative with it I suggest modifying it so that it’s only the outline. This will allow you to color the picture as you wish. I found this link while scouring the web full of images ready to color.
Make your own. This one is very pivotal on your resources. Sometimes making one from clay is easier. You can also make one from paper maché, just keep water away from it (or seal it).
Draw an image. This goes back to printing off your own, but it allows for more control.
I’m sure there are other ways to handle this issue. If you have an idea you’ve tried feel free to share in the comments.
