Great video. Well organized and presented. Keep it up. One suggestion that I found helpful to add to your method.... I have several wooden eggs purchased from Hobby Lobby that I used to insert into the base of the spout to get the opening perfectly symmetrical where it attaches to the pot. Plugging the base with one of these wooden eggs also makes a good handle while further shaping and refining the end of the spout.
Thankyou Stan ! Was stumped as to how to hand build a spout for my first teapot - I'll give your method a go. I particularly like the way it gives me free reign to push the spout out and play with it a bit. I suspect I'll be making several before I make one I like :))
