How can I have my resin a little bit soft when cured?

Hi, i’ve been searching and watching videos for almost a week now about resin art but the only question that I couldn’t find is how to make my resin not hard as a crystal once cured. I want it clear where i can see through it very clearly also solid and strong, of course, but soft enough that i can cut it with a scissor. Soft like a gummy bear, but a little bit harder. All the videos I’ve seen is as hard as a rock once cured but nothing like what i am aiming for. I really hope you can help me out.

Thanks! 🙂
