@margo,
Thanks for that. I certainly did as you suggested. Ordered 3 DVDs... that should be enough, for the time being at least. When the package arrived... low and behold... inside the package, along with the 3 DVDs, was a dear little Dr Who scarf. Admittedly it was only 5 1/2 feet long, not counting the fringe, but the best part of it was now I can actually see the exact colours. The ply must have been 1 or 2 ply the yarn is so thin. The scarf even had a BBC "Doctor Who" "Limited Edition" "Collector's Scarf" label sewn onto it. My next project is to take the scarf along to a knitting yarn store and try to buy matching colours. Wouldn't it be great to just order from somewhere the proper colours in pre packaged yarns? Meantime I'll have to do it the old fashioned way. I'm going to have a hard time finding the "rust" colour which is like a butterscotch or burnt orange shade, and the green, a sort of yukkie green. Onwards and upwards I guess. Tks for the reply.
