I found two things on making dough bowls (or dough trays, or bread trays, or simply "bowls") starting on page 93 in the chapter on Woodcarving. One has a drawing with some dimension info, all about tools, splitting the wood, carving. The other has a series of photos. I didn't read it all but the second guy said usually used yellow poplar but also liked walnut.
This is the edition I have:
It's hard looking through Foxfire books without getting totally distracted. Chapters on the various wood species in Appalachia and what they were used for, about chestnut, making a foot-powered lathe, making instruments from scratch, metal working, ceramics, bee keeping, raising sheep, cooking, snake handling... It's been years since I read them all but I could easily read them all again, starting today if I let myself.
