Knit Simple magazine has an easy to follow knitting 101 series and one of the posts is about correcting mistakes. After looking at the illustrations, I think I might be doing this:
And maybe a little of this:
KnittingHelp.com has several great videos to help correct even more problems that I didn’t realize I had! (like twisted stitches… but I’m sure I do).
Knitty.com gives specific tips on dropped stitches (and the author shares my dislike of knitting the same 12 rows over and over and over…. ugh.)
If you know of any other good resources or tips, let them here!
