Jean-Philippe, When I push the crown of the hat (the blob) into the brim (rolled out putty sheet) I did put some superglue where the two meet each other. Once the putty is cured you could also add a small amount of putty to further seal up the gap.
Anders, Thanks it fits well. I am now sculpting the hand that will be holding the tricorn, more pics to follow.
Jason, Thanks, There are quite a few events in the Western half of Pennsylvania alone. There is one down state the weekend of the 4th, unfortunately I'm unable to go, to bad, it's gonna be a good one. There is another towards the end of July at Fort Niagara in New York state that I plan on going to with camera in hand. I do have some F & I War related things I'd like to pursue with some of them possibly being 2-D work. Much more later.
Steven & Leigh, Thanks for the kind words.~Gary
