I love the potter's wheel, since it was added to the game it has been one of my favorite DST features and I love how more sketches keep getting added! Even better, when moon shards were added as a material, it allowed for so many more combinations. Last QOL update even improved the recipe of the existing boss figures and added more boss figures, which I was very happy about!
I think there's a lot more potential with the feature though, some resources in the game could work pretty well as a sculpting block to allow for more variety with materials and especially colors! So here's a list of few them that I think could work well:
- Thulecite: this one always screamed "sculpting block" to me. I think it would fit perfectly and add a very interesting color compared to the current options.
- Gems: red, orange, yellow, green, blue and purple gems would look similarly to moon shards and they would add very colorful options. the iridescent gem could also be used, though it would look solid, and I think it'd be incredibly pretty!
- Ice: sculptures made of ice are like, the fanciest thing ever! it would make figures look very interesting, having a white outline instead of the usual darker one. Ideally they wouldn't melt, since having to replace them would be annoying.
More material suggestions that I don't think would fit as well as the previous ones, but could still work: gold nugget, moon rock, beeswax, salt crystal.
