Novice soapmaker but looking to learn!

I've made a few batches of soap in my nascent career, including three batches of bar soap based on this recipe from Soap Queen as well as three batches of this "Castile" soap. I'd love to branch out, try different recipes or experiment with different blends or ratios, just feeling reluctant to fix what isn't broken.

I'll be making a new batch of bar soap soon and will be sure to post updates of my progress. Let me know if you've got any sweet recipe selections or blends to try!
