Well, that was very strange. Just lifted a picture perfectly innocently to see if it would load up. And it did. This I must try again!

Well blow me down. There's a wonderful set of bobbins! Mercy me, and all I did was nick it. Oops. I suppose it might be under copyright. I'd better link it then. Here we go: a full and proper reference. Erm, my HTML is still a bit duff so any of you bright sparks out there wanting to tell me how to get the text aligned right next to the picture, feel free to do so. Thanks. No Smart Alec remarks please. It may not look astoundingly beautiful but I've sort of worked it out. Ain't I clever?
