A few weeks ago I asked a question about why I always had problems when winding my films onto the reels. The films jammed and jumped out of the outside groove very, very often, with the resulting crinkles, wasted time and aggravation. Well, I think I found the reason: when winding, I had fallen into the habit of turning my hands in opposite directions at the same time, instead of first turning the right hand, and THEN turning the left hand towards it to "close the gap", and start over. Ever since I started being careful with that, I didn't have one problem. So far. This may seem like a trivial matter and an obvious cliché for experienced people, but I thought I'd share it for the benefit of those who experience the same problem. Don't give up the plastic reels yet (as I almost did) just watch those hands. Live and learn.
