I make custom pots in the winter, new to this forum been a Mirai member for 5 years. Another member mentioned I should come on here and offer my services. I build gardens the rest of the year so my website awengarden.com doesn't show much of the bonsai pots but happy to share examples of crescents I have made. Or you could Google username NEBeech Mirai and custom pots to get an idea. If your still looking for a crescent let me know as I am making a push before repotting season starts.
