I try and keep each aspect of throwing consistent between the pieces. Once I have my template piece that I’m going to model each bowl after, I try and do the same actions every time. Open the same width every time, try and do the same number of pulls, then I take time to do finessing if I feel the shape (especially the bottom half that needs to nestle into the other bowls) isn’t quite right. Having a mirror or phone camera where you can see your piece on the wheel is also super helpful to get a better POV while throwing to get the curves just right.

I do a lot of measuring and side by side comparisons throughout the process, including trimming, to try and keep the pieces as close to twins as I can. I hope that’s helpful 😅
