Sounds like a fun project. Maybe start with a small wooden cup, maybe a bit thicker on the sides so it doesn’t feel flimsy, but not too heavy. A wooden handle could be a nice touch—carve a smooth, shallow groove, so it’s comfortable to hold. For the straw, a bamboo stick is lightweight and natural; you could cut a small notch at the top to keep it from slipping out. Add a simple etched pattern on the rim—something like a tiny leaf or wave design, just enough to give it a cozy look without overdoing it. Keep the surface sanded smooth so the bubble tea stays cool. Finish with a light coat of food‑safe oil to protect the wood but let the natural grain show. How does that feel?

Glad you like the idea. Just make sure each edge is even and the finish is smooth; that way the cup stays cool and feels comfortable. Good luck—let me know how it turns out.

Sounds like a solid plan. Take your time, and I’ll be ready for the photo. Good luck with the sanding.
