Is it necessary to follow the recommended size of knitting needle yarn?

I brought a little knitted wool and it is suggested to use a size 13 (9 mm) knitting needles.'m knitting a hat. Do I have to follow this recommendation? If you use a size 7 is not working? Why? Thank you very much, I am trying to avoid buying a needle size when new start a new project!

Definitely not! This is the good side of that caliber all "" tangle that drives some crazy weavers. Each weaver weaves otherwise, either freely or (EZ says looser is better, so cold!) That will give your indicator of a thread. So you can think more broadly … weight wool yarn, you can work better with a size US6 or you may have to go way up a 10 if well woven. I guess there's bad news in that, too … you might as well just buy the sizes of 7, 8, 9 and be done with it! And Here we assess – If the employer says it is working to use 13s, but it also provides a measure of stitches per inch, this should work As. I'm going to guess that this is a very strong little wool and unless you're a very loose knitter, 7 will not work. But give it a try … work a bit on the model and see how it goes. This is not rocket science and there is no point police. And in point, you can undo and retouch … all good news. Overall, I like to think in large terms – If you look at something like this: check out the thread http://www.knitpicks.com/knitting+yarn.html weight. I know for myself I'll use a size 1-4 for a fingering A 6 to 9 for wool, etc. are often very lazy uses "close is good enough" for the method to measure but is going to be completely obsessive when is necessary (1 / 2 mm makes the difference sometimes!) So no, it is not necessary to follow the instructions. But yes, you probably end up buying lots of needles! See the following sites for needles to bring joy! Happy Knitting! Anniessa
