I love my dpn. No problems with them.
Reading some of these posts makes me realize where the problems can be, though.
The trouble disappears with experience, never fear!
For those, that fear to loose stitches off the needles:
Do you drink wine? Or at least have some cork?
Cut pieces of cork (slices or smaller) and pin them on the rear end of a needle when knitting. [small pieces are good, because they don't get in your way and do not tend to be pulled off] Or on both ends of a needle that is in the back of the work. Pull off the cork when you need the needle.
It is cheap, it works great, and when the holes wear out and the things son't stick anymore, use them for bigger needles and take new ones.
cork also does not give a sticky feeling to needles, so it does not prevent your work from gliding when you want it to!
I have my ways of preventing the dropping (or just deal with it), but when it gets tricky I think of the cork (and am usually too lazy to go to the kitchen, anyway).
Oh, by the way: there are wooden dpn (bamboo and other wood): those are a lot less slippery! Might be worth a try!
And since I am German, I can add to the language matter:
sock needles would be called "Sockennadeln
" in German, if southern Germany also "Strumpfnadeln
Most likely your sets will say "Nadelspiel
", though. That would mean "game of needles" - or more correctly: set of needles.
From all I know German dpn-sets always have 5 needles and the German way is to have the stitches on 4 needles and 1 for knitting off with.
In the US and videos I have seen people with 4 needles in a set, though. The stitches on 3 needles, 1 for knitting off. Well both works, I prefer the 5 needle method.
