Hi Tree,
Yeah, The blend tool will round off the corners nicely before I trim the surface of the cylinder with the wrapped curve. If the bottom is a different size, I would just have to do a second curve for the bottom length, then loft between them. Then I can extract the edges of the loft and trim the cylinder surface with the new edges and use the trimmed piece to create the label. Can offset it out and shell it if you want to give it thickness.
