I am working on a blanket and made an error, but am having trouble diagnosing and fixing.
Most videos I find direct how to fix a dropped stitch, but they seem to indicate you have a loop to start with, and one that could be pulled out even further if you don’t fix it. I don’t feel like mine is that case, which is making it hard for me to figure out the best way to approach it.
I’m trying to decide if I should just take out the last few rows so I don’t have to fix it at all, but it’s probably an hours work (I’m a beginner). Alternatively, I can take it to a knitting shop in the next town over and maybe get help?
Is it worth fixing, or should I just pull out the rows to get back to the problem area?
Hi, welcome to KH. Looking at your picture I can’t tell that you’ve actually dropped a stitch. Is your stitch count down one? On the left it looks like maybe the first stitch on the needle got slipped in which case you could just pull the yarn through it now, or maybe that’s your working yarn going across. Anyhow, start with counting and make sure you’re down a stitch if you’ve not already done so.
Welcome!
Just looking at it I don’t see a dropped stitch. As you mentioned, there doesn’t seem to be a loop at the end of the ladder between the needles. Is it only the ladder that you’re concerned about or is there something else that’s doesn’t seem quite right? The extra yarn can be worked into the stitches on either side pretty easily.
If you decide to take out a row, this method of tinking (knit spelled backwards) works well (and believe me, I know tinking).
Thank you for the suggestion! I didn’t think I had dropped one, but since I’m new to knitting wasn’t really sure where else to look… I will count my stitches!
salmonmac- Tinking! That is exactly what I think I’ll need… 
My last Google search was the best way to undo everything, and this seems it might be the safest way so I’m not getting anything twisted.
The ladder area is the only area of concern, and as usual, appeared out of nowhere.
Feel free to ask here. Google searches can eat up lots of time, and often an experienced eye can see the problem. salmonmac and others here are really great and the rest of us try to help where we can. Overall it looks as if you’re keeping even tension. You wouldn’t have noticed it so much if your other stitches weren’t really, really nice. You’re off to a great start.
