I have been making a lot of the same pitcher form trying to fine tune all of my ideas. One of the main things for me is making the handle continue the line created by the bottom section of the pot. This form needs a handle to complete it, but if the handle is wrong it throws off the whole pot.
I have also noticed that I like the pitchers to be more narrow and cylindrical shaped. I think that on the wider ones the angle created by the two planes meeting is too sharp visually. I made a couple pitchers in various sizes to create a sort of set. I'm not sure if I will photograph the finished pitchers as a set or as individuals. But I think if done well, sets like these can be a pretty powerful image.
