If you’re working stripes – and they’re only a few rows (say, no more than 6) it’s nice to avoid weaving in all those extra ends. Carry up the yarn instead of cutting it!
Note this only works for an even number of rows between stripes. If you have an odd number of stripes, the yarns will be on both edges and this won’t work. But, many (most?) patterns switch yarns on the same side for just this reason.
Here’s how to do it (it’s just one step although I gave you 5 pics)
This creates a nice, tidy way to carry the yarn and you hardly see it.
If you’re joining a new color, lay its tail down to the right, with the other side aligned with the original color. Wrap it just as if both yarns were already attached.
Give it a try and let me know what you think!
