How to fix a hole in a sweater

I just finished a sweater that actually fits me and it got caught on a chair resulting in a hole. How can I fix it??? It is stockinette stitch the hole is located at the edge of an intarsia flower design any hope?Thanks in advance Madge

If the yarn didn’t actually break, it just snagged which pulled the yarn tighter from the surrounding stitches. So just work it back into them on both sides, using the tip of a needle or tapestry needle until the hole closes up.

Another idea, if it is actually a hole and not just a pull. Could duplicate stitch fill the gap. That works on holes sometimes and covers them unnoticeably.
