I'm working on the tri-loom today, making a shawl in neutral colors for Shane's Granny. It was supposed to be done for Christmas, but well, I kind of ran out of time. So it will be a New Year's present.
In any case, it occurred to me that when I first started with the tri-loom, I had to look up how to change colors. So I snapped some shots just a bit ago. Here's how I do it:
First off, I plan out my color changes ahead of time, so I get an even plaid when I am done. I mark the pegs where the changes will take place by putting a paper clip on them. If you have smaller pegs, a rubber band or a piece of string may be a better choice. But in my case, the paper clips have stayed in place through several shawls.
So, when you come to a paper clip, stop weaving for a moment and get out your next color of yarn.
Now, let your current color of yarn dangle down. Cut the yarn so you have a long tail. If you are going to fringe your shawl, make sure the tail is long enough to hide in the fringe. If you are not going to fringe your shawl, make sure the tail is long enough to weave back in later.
If you're using Lion Brand Homespun, like I am with this project, tie knots in the cut ends of your yarn right now. This yarn is lovely, but it frays like nobody's business if you don't control it with a knot!
Grab your new color of yarn. Let a tail hang down in this color too, and pinch the two yarns together right at the bottom peg.
Tie a loose knot at this spot.
Tighten the knot, so it snugs into place right where the yarn will bend around the bottom peg.
Ok, now you can go back up and continue weaving as normal. Your old color will weave down to the knot, and your new color will continue across to the other side. The tails will hang down below the loom, and will be hidden in the fringe or woven in at the end before you take your shawl off the loom. It feels odd to have the color change take place there, but trust me, it will work out symmetrically in the weave.
I'll post pictures of the finished shawl in a day or so, when I get it done. I think it will have a nicely elegant feel to it.
