I used a ball of Caron Simply Soft Quick in black and a scrap of yarn about 8 inches. I untwisted the black yarn a bit (it is a thick 2-ply yarn) and slipped one end of the scrap green yarn between the two plies of the black yarn. I then proceeded to untwist the black yarn the length of the green scrap. I then held the two together and let the black yarn re-twist back up enveloping the green yarn in the twist. I then threaded the second end of the yarn in between the two black strands to secure it further.
I think this would make a fun gift ball of yarn to give someone. They wouldn't know what was inside the outer layers.
I was thinking about trying this technique next with just one color family of scraps.
And now if it would only get cold enough here in SoCal so that I could wear my scarf instead of my yard gargoyle!
So this is my trick that is actually a neat trick!
Happy Halloween to all ya'll.
