I've had the same, where they aren't all at the same thickness, which is really annoying. I've started using one of the little frothers for the small amounts but it can sometimes add a bunch of bubbles. It's trickier than one would think. I think your soap looks cool! And yes, another reason to make more. Looking at those pictures again made me want to try again so I am just waiting for cool down before I give it another go, for a butterfly.
