Do you like weaving in hundreds of ends when you work with stripes? Me neither! I almost always carry the yarn up the side.
Here is how I do it. I have found that by wrapping every row the alternating colour creates a smooth and invisible way to avoid cutting and weaving.
Here I am knitting Charlotta, it requires 8 of the yellow stripes and then 2 purple.
My next row is yellow, so I need to carry the purple up the side. I happen to be up to the sleeves and I don’t want the carried yarn to hang out the side of the work so choose to carry it up on the second stitch.
I knit the first stitch.
Then I insert the needle into the second stitch.
I wrap or twist the two yarns around each other, the yellow goes over the top, then underneath.
