Question - How can I rip back ten rows and not lose my place?

Locate the row below the one with mistakes.

Take a needle several sizes smaller than the one you are using to knit and pick up one leg of each stitch in the row. If you do not have a smaller needle you can use a blunt darning needle threaded with a length of smooth, sturdy yarn.

Once you have picked up all the stitches on the row, you can safely rip out the offending rows.

You can knit directly off the smaller needle as you continue your work or you can transfer the stitches back onto your regular needle.

Knitter's doing complicated work like Lace Knitting often place a safety line through their stitches every three or five or ten rows just in case.
