Hello!
I’m relatively new to knitting and just found this site. I’m trying to knit some “longies” and have had to frog back due to messing up my pick up and knit stitches. I used the method of inserting a smaller circular needle into my destination row, and set it up so that the needles were in position to begin knitting at the center back as they are supposed to do, but when I unravelled, my working yarn is way over on the side. I can’t figure out what to do-can anyone help? Thanks so much in advance if you can.
Sounds like you need to either work part of row or unravel part of one more row to bring the working yarn form the edge to the center of your work.
Move your sts around so the working yarn is on the R hand needle.
Thanks to you both - What I did was to place a marker at the center back and then transfer the 16 stitches from the right needle to the left so that the working yarn is in the correct place. But now, won’t those extra stitches make an extra ‘short row’ type thing as I go around since I had inserted my needle all around in an even row to frog back to?
More than likely. This happens in almost all projects. Somewhere along the way you work one half and not the other and end up with one more row on one side or the other, but is usuually barely noticeable in the end result.
Yes you’ll have a few sts with an extra ‘row’ but it won’t show up when you’re done. It doesn’t matter, happens all the time.
Alright ladies, thank you so much, I will trust you on this one 
Hard for my perfectionist self to think of the asymmetry but I feel reassured!
