Rich:
Glad to hear that you are excited to be back in the shop and trying to create what you see in your head.
I have never seen your work, but if you are, or have been, artistically blocked, bogged down in details, etc., you are a creative person trying to express his take on a decoy, which makes you an artist (whether you like being called that or not. When you get to my age and have been called a lot worse than "artist" you will actually embrace the term.)
It gets back to that old concept of "comfortable in your own skin". If you really find yourself sucked down that detail ridden road, try this: set a time limit on various parts of making and painting the decoy. There is one heck of a difference between doing the best paint job you can in 1 hour, versus 3 hours, versus 8 hours. When I made and painted decoys for money, I had several antique dealers who had me paint both new duplicated wooden decoys and stripped, primed antique decoys. At that time I charged by the hour and the dealers would hand me the decoys and say, "give me one hour paint jobs" which meant a $10 paint job. Sometimes they'd ask for a 2 or 3 hour paint job, or say, "give me the best $50 paint job you can." For the one hour paint jobs, they knew I had to have a minimum of 6 decoys, same specie and gender for the $10 apiece price to apply so I could set up an assembly line and minimize down time and mixing time per decoy.
First, you'd be amazed what you can do in an hour of painting, if you plan it out and already know how to mix your colors, AND you have multiple decoys to paint in an assembly line process. But by the same token, that time limit forces you to stylize some details, omit others, and use some old time techniques like sponging, combing, stippling, etc. It can also change your whole perspective on what a "good" paint job is. I have done some "great" one hour paint jobs, but they certainly wouldn't be considered "great" as compared to what I could have produced if I had taken even three hours per decoy. With the exception of a few decoy makers like Crowell, Wheeler, Enoch Reindahl, etc., I doubt if most of even the hallowed, big name carvers took more than an hour, total time, to paint each decoy, not if they were doing decoys to sell to hunters anyway. Think the Ward Brothers, who had a sanding belt running around their shop to save time in finishing the birds took multiple hours to paint each decoy? I kind of doubt it.
One of the best pieces of decoy carving and painting advice I ever got was from Jim Foote, who could carve and paint decoys faster than most anyone who was competing back in the 1970's and 1980's. I loved his free ranging, impressionistic, and risk taking artistic style (the exact opposite of his friend Larry Hayden who as a commercial artist, planned everything, was precise and tight). His suggestion was to carve and paint at least 6 decoys of the same specie and gender at the same time, starting with the heads. He urged me to rough out the heads, then look at them all and rank them from best to worst. Then he urged me to take the worst head, and as I added detail, to try to make it the best. Ditto for the carving of the body, ditto for the painting. By doing multiple decoys at a time, you don't get invested in one, you take more risks, and if one turns out better or worse than the others, so be it.
That advice has really made a big difference in my carving and painting, at least in my satisfaction with my carving and painting. Maybe it will work for you, maybe not............ Just some shared solutions that work for me.
