I am making a very simple hat in green with a large yellow "O" on it. What is the best way to switch between the green and yellow? What I am doing now is having two skeins attached and one stitch before I have to switch i catch the end of the next color in the last stitch of the color I am currently using, then I proceed with the new color and repeat as necessary. This leaves long strings stretching across the back of the cloth.
If you're knitting in the round this is the method I use to knit fair isle. The problem with knitting in the round is that you usually carry the yarn all the way around and if you're doing a single O then you might not want to. http://www.philosopherswool.com/Page...andedvideo.htm
If you're knitting flat so you'll seam then you'd use fair isle method. There's a video under advanced techniques on the tab at the top of the page.
When asking questions ALWAYS post the name and a link for the pattern if you have it.
You can avoid the long loops or floats across the back of the knitting by "catching" the carried yarn every 4 sts or so. You do that in a way similar to the way you change colors. Here's a video to show it.
