Lifeline woes!

[afuna]

I love the idea of lifelines, and I've used them before in projects with a thicker weight. This time though, I'm making a very lacy shawl in laceweight yarn, used a lifeline of dental floss, and I'm running into problems.

Yesterday, I found a dropped stitch that had fallen some five rows back. While debugging that, I found another error in the repeat just above my lifeline. So much relief! I ripped back fifteen rows to my lifeline, and then realized that the dental floss wasn't holding the shape of the loops well enough.

It's not an issue with the lifeline having been picked up along with the stitch; the lifeline was sliding back and forth in a straight line before! It's more like the loop of the stitch has been pulled out of the stitch below, though they're still being held together by the lifeline. The lifeline ends up being twisted around one of the strands, and then becomes untwisted if I pick up both stitches and make the knit/purl for that row.

I'm three stitches in, and it feels like it would be a lot more pleasant to frog everything and just restart, but I want to make sure I don't run into the same thing with lifelines in the future.

Is it possible to use a stiffer material for a lifeline? Say an interchangeable circular cord, or maybe some wire?

Yarn swap gushing here!

[cme]

Did we ever have a post to gush about the yarn swap this year? (I couldn't find one.)

Anyone mind if we declare this post the Yarn Swap 2011 gushing post? Comment and tell us about how the swap was for you!

(I want to gush, can you tell?)

EDIT: The magnanimous sporkyrat has authorized me to create a yarn swap gushing post! Since this post has some excited gushers already, let's make it this one! Tell us about what you sent, what you got, and what you're planning to knit!
