I recently was working a project that required many color changes. Typically, I would fasten off at every color change and weave in my ends because I just wasn't happy with the other techniques, but I wasn't in the mood to weave in all these ends this particular time so after playing around with it a few minutes, I came up with a technique I fell in love with. If not for this technique, I probably would not have attempted such project or any futures ones with multiple color changes. Before I start, typically to work a yarn carry you just drop the color and pick up the new one and then switch off as you are ready, but I don't like working in this manner because it leaves strands of yarn vulnerable to getting snagged, and creates an unslightly view, even though it's on the inside of your project and not really seen. I came up with this technique to avoid all of the that, and create a seamless piece. In the images I am using an I9/5.5mm Crochet Hook and Hobby Lobby's I Love This Yarn in Red, Jelly Bean [Green], White and Turquoise, but the technique is universal.
