[Nfb-krafters-korner] Changing color in knitting

[Tracy Carcione]

This is my understanding of changing color in knitting.  I did it once,
changing yarns, but that was a while ago.

Knit along with color A. When you want to change, join color B.  Twist it
once around A, then knit with B.  If you're changing several times in a
row, every 2-4 stitches, then carry the color not being used along the
back of the work, loosely.  Always twist the 2 yarns once when you change,
or you will get a hole.
If you are knitting color B in a column, and then there's a lot of A, then
another column of B, you'll need 2 balls of B, one for each column.
This is much easier to do knitting flat, because you can pick up the color
where you left it on your way back along the next row.

I hope this is clear.

I'm not very interested in colorwork, as I can't see it.  I've been
thinking it would be neat to do it with yarns of different textures, so it
would mean something to me, but I haven't found any 2 yarns that are the
same weight, but different enough in texture to feel a clear difference. 
Except where one is very scratchy, and I don't like that.
