I found in my trunk the remains of yarn of one brand, but different colors. About half a Motochka each. Not long thinking, decided to put it on a scarf. And at the same and photographed the process itself.
Knit a chain of air loops of such length as you want to make a scarf. In the beginning and at the end of a chain we leave a line of a thread-it will be fringe. Cut the thread.
Next, attach a thread of the next color. Do not forget to leave in the beginning and at the end of a line a thread equal to the necessary to you length of a fringe. Knit columns without a scale.
Cut the thread, turn the wrap and attach the next color. I decided that it would be more interesting to look when alternating the main color and secondary. I'll have the main gray. Knit columns without a scale behind the back wall of a loop.
I tried to take pictures large and marked the back wall of the loop with the arrow.
Turn the knitting, attach the following color. Again knit behind the back wall of the columns without a scale. You get a drawing, something resembling a faceted gum spokes.
Continue knitting to the desired width of the scarf.
That's what I did.
You can tie a scarf of one color, two or three-to your liking. When knitting a single-colored scarf is better not to leave the fringe, and make it on the already finished scarf.
