Meg, taught me this technique. Its brilliant and so much easier in the long run to weaving in ends with a darning needle or crochet hook. She truly is gifted. Thank you Meg!
This technique can be used for doing frequent color changes and when tails are about 2 inches or so long.
The instructions are written for English style knitting (my preferred style), however can easily be adapted for Continental style knitting.
When adding a new color, leave at least a 2 inch tail and complete the first stitch.
Next insert needle into the next stitch, take the tail (of the new color) and drape it over the the right hand needle toward you, the tail will be crossing over the working yarn (shown above), then complete the stitch.
Insert the needle again into the next stitch, take the tail of the new color and drape the tail over the working yarn away from you, the tail will be crossing over the working yarn again (shown above).
Continue to move the tail back and forth over the working yarn prior to completing the stitch for 10 to 15 stitches or until the tail is too short to manipulate. Do not cut tails until piece has been completed and blocked (either wet block or mist block). This will set the stitches, so they do not wiggle out.
Once blocked, tails can be snipped.
There are some YouTube videos showing a modified version of this technique that will also work well.......HOWEVER.....I found the results to be a bit bulkier fabric and sometimes noticible from the right-side
Happy Color Knitting!
