How do stitch holders work?
The removable stitch marker, like a safety pin or even a bit of string that you can untie, is used to mark a stitch itself, or a point in the knitted fabric. It opens up, so it can be attached to a single stitch and left in the fabric.
What does it mean to rejoin yarn in knitting?
To ‘rejoin’ yarn, you don’t really need to attach it, just leave a long enough tail to weave in later and start knitting. The first stitch may seem loose but it won’t pull out and after you’ve done more rows, that will anchor it in.
How do you break yarn and rejoin?
Lay the new yarn across the needle, so that its yarn tail sticks out at the front of the knitting. Then hold both the old and new yarn together as if they were one big yarn strand. Knit three stitches with the joined yarns. Let go of the old yarn, pick up the new yarn and continue knitting with the new yarn.
