I don't know

if this will work for you but has for me when I have goofed on a part of one of my socks, the last pair 3 times!

A more experience knitter taught me to take a DPN one size down from what I was working on & pick up the stitches the row below where I needed to get back to. Do this on both sides if you are working on 2 circs. Then just frog

it back to the DPN and whala! pick up at that point & start knitting again.
Hope this will help & keep you from tinking over 300 stitches.
