Cool style Dave!
The construction of the pour is so random you really don't know what will show up until it is finished, makes for some great patters and colors!
I would liked to see more of the cholla pattern exposed since it produces such a unique pattern. Maybe you could boldly go where no one has gone before and try flattening and laminating the stuff like they do with bamboo plywood?
I know, crazy talk 🤠
Lower "failure" photo looks like a great item for Halloween next year 👍
