Hi All,
I am about to start knitting for my gorgeous 5" doll but Im finding it quite daunting to get some information. They say its best to use one ply but have heard back from somebody today that rayon crochet thread which is one ply would be good to use as well. Now comes the question..... what knitting needle size is good for one ply? Cant seem to find out what I need. Im in the US. So any help would be greatly appreciated.

Im at the point of pulling my hair out:eyes:

Thanks all
Hugs
Lulu

One ply doesn't really mean anything to me because you can have a worsted weight one ply or a lace weight one ply. Giving us the weight of the yarn (fingering, sport, DK, etc.) helps a lot.

Here's a yarn weight guide that includes recommended needle sizes that might be all you need though.

If you're talking about ply as in weight, that would be a thin laceweight. Which would probably take sock needle sizes - under size 2. You might be able to use baby/fingering or sport weight yarn, which can be knit with sizes 3-5.

If you are making doll clothes for a 5" doll, I'm assuming you are going to be using very fine yarn and want to get a very fine stitch and a very fine gauge. If that's the case, there are very skinny needles available from .25mm - 1.50mm which will best suit your purpose. Try this: http://miniatureknitting.com/dpn.html

Thanks folks for your help.
The Yarn I have at the moment is Sublime - baby cashmere merino silk dk and I have just read on the label that it recommends USA size 6 needle. I guess its going to be a lot of trial and error on my part lol.... but thanks for all the useful links.
