Sometimes when using a skein of yarn, you'll come across a point in the thread that was cut during processing & is tied to a new piece of matching yarn.
Normally it's no big deal, especially if it's a solid colored yarn, you won't even notice.
But....tonight I was working on a beanie/hat & was trimming it w/ this lovely jewel toned, variegated yarn. It was working out quite nicely that the colors were matching up w/ each 'round'...then that bump!
The yarn ended @ lavender & 'whoever', tied a blue edge to it! So it totally changed the color pattern it was making on the edge of the beanie.
It was looking so pretty too.
