I made all new pattern pieces and made them consistent (arm ends same width as hand ends, etc.) and I'm happy with these hands. I made boot and shoe pattern pieces as well as collars. Plus, I got everything in very securely and with nice looking seams. I'm quite jazzed. There will be many more of these.
The most important tool in making these, outside of the sewing machine, is a roach clip. Amazon calls it a hemostat (and I'm sure doctors and nurses do, too) BUT we all know it's a roach clip. I ordered a new longer one that just arrived. The legs will be easier to turn on the next one.
