For some time now, but especially since knitting Nuvem (silky laceweight yarn on slippery 3.5mm metal needles) I have come to enjoy picking up dropped stitches. I don't drop very many, but sometimes, especially if I'm watching a movie and knitting quickly, there are a few casualties. Christine and I were talking about this and she thought a post might be helpful to any new knitters who are following, so if you do indeed find this helpful, it's thanks to Christine.
FIXING DROPPED STITCHES:
If it's just stocking stitch or garter stitch it's usually a very quick job to fix the dropped stitch...
If there is a more complex pattern (so the stitches are not all the same), tiny stitches, or if there is more than one dropped stitch, I find it reassuring to insert a lifeline (as in this post) so I can fix one stitch at a time without worrying that the others will unravel any further.
I had the foresight to take some pictures the last time this happened:
(Here's the link to the mini crochet hook pictured, very handy for this situation!)
DROPPING STITCHES ON PURPOSE:
The exact same principles apply if you spot a mistake further down your work. Once you've identified the rogue stitch, it's easy to unravel back to the error, fix it, and then pick the stitches back up to the needle. Again, a lifeline might reassure you the first time you do this, as the stitches can't unravel any further back once that's in.
