Terri, I had an MRI several years ago and I am not fond of closed spaces (used air). The one I went to had bright lights inside the tube and a fan blowing cool air over you. I found if you close your eyes before going in w/ the light and the air it wasn't to bad you could psych yourself into not being in the tube.
Marietta, I almost never follow a premade pattern (except very complicated paper pieced blocks like in my avatar) I almost always make my own pattern from pictures, sometimes I make it all up in my head (don't start w/ a picture) and many times I'll start w/ a picture and just go off the rails changing stuff.
