If I want to create some knee high socks does the size of a needle really matter? For instance if they recommend the size 3 knitting needles, but I have size 2 knitting needles is that okay in such a project?
Size of knitting needles
If use use a smaller needle the fabric will be denser, but it should still be okay. It will make the sock come out slightly smaller though so keep that in mind.
Check the gauge, check the gauge, check the gauge!!! You may find that the 2s work fine, but if you are a particularly tight or loose knitter, you might spend all that time on the socks and find out that they are unwearable. Well, 1 sock-- I guess you’d try that one on before starting the 2nd:) .
If that would be the case, I hope, I would.
