don't ever worry too much about the specific yarn. You have it in hand, so you know what project it might be for.
Knit a swatch (you don't really need to anymore, Jan found the specs) and find any pattern that uses that swatch measurements.
At garnstudio.com it says right under the pics in the preview what stitch count they use! Super easy.
In European patterns they sometimes give a specific brand. But usually you just care for the meters per 50g and the swatch.
I truely have NEVER searched for a pattern with the NAME of my wool / yarn to start the search with. This seems to be a very American Knitter way of going about it. No offense, you just make your life too difficult, and that goes for some of the knitters as well as the pattern makers. Take it easy!
And if the gauge is not right: re-write /-calculate the pattern. That often does magic!
Especially with kids cloth you have one big advantage anyways: They lable a lot of different sizes. If your swatch comes out 15 % bigger than the instruction, for example: knit a pattern size that is about 15 % smaller (by instruction) and follow it like this:
the number of stitches or rows you take from the pattern that your swatch lead you to, the number of inches in some parts of the instruction, you take from the pattern that is given in the size of the kid (since you want it to fit and not be stubby or long).
Volia: you have a fitting kid cardigan, pants, skirt, whatever without doing all the math.
For patterns like that I print the instructions / copy them and highlight the numbers I have to follow as long as I remember, am capable of concentrating and want to do it. Then you just go to knitting!
