A little mosaic knitting
I always thought that knitting diagonal stripes would be very tricky. Yes I could see that Fair isle knitting would work, but I wouldn't fancy knitting the wrong side, I'm sure I would not only get my threads in a tangle but my mind too, working out which way the stripe was going.

So imagine my amazement when I found this great little trick with mosaic knitting. Not only is it really easy to do , once you have done the first 4 rows , but there are no tangled threads and you can't go wrong really.
And the wrong side is nearly as cool as the right.

My daughter, Michelle watched me this morning whilst I worked a couple of rows and she summoned the process up in a way that I never thought.
She said that whilst you knit the row in one colour you leave stitches behind so that they could be knit in the other colour later on. I think she summed up mosaic knitting rather well.
The article below nicely explains the difference between fair isle and mosaic knitting when working the same pattern. It's a great intro to mosaic knitting.
