I taped this tutorial for my other blog and then realized that, oh hey, it might be useful for handknitters too! Duh!
Snagging tends to happen most often with loosely knit garments, particularly if the yarn is a bit slippery, so I feel like I don't have this problem as often with handknits...but it can definitely happen. Fortunately it's really easy to fix, and probably much easier for knitters who already likely know how to "read" stitches ;-)
Apologies for wandering off camera a bit towards the end- new set-up, still kinda figuring it out!
