Newbie resiner, but its something I've wanted to do for a very long time. Im loving it so far and considering trying out a craft fair or something. But I have no idea where to start or how to make sure the quality is good enough!

How do you go about pricing? I’m doing a project for myself, and now that I have the form I thought I could sell some duplicates to make my money back from the project. Issue is it’s a giant 10ft tall light up rainbow…so I can’t really compare similar pricing. Do I just post photos online for preorder?
