So, yesterday, I talked about what a lifeline was and why it was important. I failed to mention how to insert a lifeline.
You’re thinking there is only one way to put in a lifeline, right? Thread a needle with some contrasting color yarn (I use lace weight yarn! You can use dental floss, embroidery thread, etc, what ever you have at hand!) and carefully weave it into all the live stitches (missing ALL of your stitch markers, don’t forget!). You can certainly do it that way, the hard way, but some interchangeable needle companies have come up with cheats.
