I imported a model from another program and it didn't include any seams or a UV layout. When I unwrapped it, there were a lot of left over polys and I want to try and clean it up and have fewer islands to deal with. (e.g., I want larger islands with fewer small pieces that are unconnected and logically should be connected). The reason I want to do this is to make editing the texture in photoshop easier and more intuitive.
To start with, I'm looking at jewelry on the character model as shown below. It's kind of a complex shape and I'm struggling to figure out where to put the seams. I started with the loop cut tool and created a seam for every loop edge the tool could find. However, I'm not sure what to do next. Edges tend to go inside other shapes where you can't see them, and the ALT select is not a reliable method for getting the seam all the way around the mesh part.
