Catherine, you beat me to it. I attended that online lab, and it was very helpful. The key is that as long as you can relate the various items in your shop to each other, then it's okay to mix it up a bit. For example, it'd be fairly easy for me to add hand-knitted accessories to my shop because in essence, accessories are what I'm selling to begin with. I'd redo my sections and then add links back and forth between jewelry and the knitted items. To keep with my theme of "repurposed, reclaimed, rescued," I might choose to make these things from reclaimed yarn. Hmmm....that's actually not a bad idea. *wanders off muttering to self*
