I've made a few kids' mugs. These chubby-handled mugs are smaller and a bit sturdier than those for grown ups and they have some little garden-inspired illustrations on them. I think the idea was planted when I saw kids' mugs on the blog of US potter Emily Murphy quite a while ago (and we have a need for them in our household!).
I have some new ones (similar but different) hopefully going in for glaze firing this week and am looking forward to seeing how they turn out!
