I like the split skins better. You can inspect the feathers easier, and look at the back (skinside) to make sure there isn't any fat/meat left on the skin. When picking out a starling skin, I like to find a bird which has glossy iridescent feathers.
As you can see, this skin was kind of oily on the backside. It is a good idea to wash the skin in Woolite, to remove the excess oil, then re-dry the skin.

Here is a bleached starling skin. Bleaching results in a lovely tan coloration.
