When I spin on the wheel I spin S \ wise and ply Z / wise. I discovered at the weekend that when I spin on my drop spindle I spin Z / wise.
Go on, ask me how I discovered this. Was it perchance when I was plying (on the wheel) the two bobbins containing miles and miles of very fine Shetland/silk that I had painstakingly spindle spun? Why yes, I believe it was.
I decided it would be easier to ply on the wheel than on the spindle. I'd already wound my first single (green slubby) on to a bobbin by hand as I only have the one spindle. I wound the second one (gold shiny) using the bobbin winder I'd bought at a guild meeting (bargain it was too) and I just began plying. I wasn't too happy with the way it was looking but it wasn't until I was about two thirds of the way through that I realised what the problem was; I was plying it in the same direction as I'd spun it!!!!!!!!!!
After a bit of a panic I decided to carry on as I was and then run it back through the flyer spinning twice as much in the opposite direction. Luckily it seems to have worked, though I think it could have taken a bit more twist. I have 452 yards there. It's a bit brighter in real life (picture's washed out) and it's beautifully soft. Just have to find a project for it now.
Finished yarn is 60gms of about sixteen WPI (ish). Spun from some of the palest Shetland grey katmogget I bought at Woolfest. One single was carded together with some lime green tussah silk and some white silk noil. The second single was carded together with some gold mulberry tops (no tussah silk the right colour at Wingham when I went). There are about eight twists per inch (again this is very "ish" as it's not very regular due to plying cock up).
ETA: Hmm I wonder if that's what happened to the last lot? I just thought it had sprung into a disgusting mess because I forgot to tie it properly before taking it off the niddy noddy but I reckon it wouldn't have gone as ubertwisty from just that as it did. (no pics of that one; too embarrassing)!
