I just typed this up to keep at work, and in my knitting bag, and I wanted to share it with you guys, my readers. I am not sure where I got this chart from, as I had taken a screen shot of it with my iPad somewhere. So unfortunately I cannot credit the source, but I am not taking any credit for the information above. The chart gives you a list of the minimum amount of stitches you can put on a circular needle (circular needles in the lengths of 16”, 24”, 29” & 36”). At work we sell 16”, 24”, 32”, 40” (and some 47”) needles, which are almost the same as these above. I think 29 & 36” are more popular in the USA, than in Canada, but I am not 100% certain. So you figure out how many stitches per inch your yarn is, and here you have a guide to see what length circular needle you would need to use for your project.
