I'm so glad you figured it out. There's no reason to feel like a dope, that could confuse anybody! Good for you! It's a very pretty shell, I'm glad you can get on with it now.
Me too!! Now I can be working on all 5 projects at once instead of just 4.
You can work on FIVE projects at once? Pardon me for asking, but are you an octopus?
Meanwhile, I'm glad the light came on for this one. Sometimes its just the worrying it around that makes it finally make sense, and that worry around often involves others, so no need to feel bad about that!
