yup. the bigger the needle, the bigger your stitches. likewise, the smaller your needle, the smaller your stitches. simple really.
Why?
20mm knitting needles are needles that are 20mm in diameter. They are also known as US size 35 needles.
I think what you are asking is how do the different size of needles affect the type of stitches you will get when knitting. Basically, the larger the needles the larger the stitches. Also, if you use smaller needles, the fabric you create will be stiffer than if you knitted with a large set of needles.
no
Your answer depends on the yarn you choose for your project.
Broomstick knitting needles are the size of a broomstick handle. That would be approximately 2.75 inches in circumference or about 7/8ths of an inch in diameter. This would be a US 42 size (I believe), or a 22.0 to 22.25mm size, needles.
The ball band on yarn often tells you what size needles it is suitable for.
No, this is an information site, not a business.
it means you have either added yarn overs or dropped stitches. it might mean you are a beginner or it might mean you are knitting lace and want the holes. or that you are knitting on needles slightly larger than you would use for a not holey fabric. P.S.: You are supposed to have holes in your knitting! The hole size is because the size of the needle. (ex: large size needles=large hole, small needle= small hole) Understand now?
I don't know, type it in on wiki answers!
If you want to go from a 14st gauge to a 12st gauge, you need larger sizes needles.
Your gauge will be different and the size of the garment will be different, unless you accommodate the larger needles with a new gauge, and recalculate the fit.
