One of F's Christmas presents from us was a rock tumbler. It has been so fun to see him use it; he really loves rocks!
Setting up his first batch of rocks to tumble.
After using the first grit.
After the 2nd grit.
F's finished rocks after all the grits. It took ~ 1 month to finish these.
I think F's rocks came out great and he has already started his next batch. This was definitely a win as far as gifts go. I look forward to seeing more of F's tumbled rocks soon.
