I’m new to knitting. I made my boyfriend a scarf. When one ball of yarn was finished, I tied another ball to it. It came undone and now there’s a hole. I have been trying to fix it and I’m just getting frustrated. Please help. It’s not a big hole but I just can’t figure it out.

Welcome to KH!
The scarf looks beautifuuly knit.
The first thing is to put stitch marker or safety pin through any loose sts. This will prevent them from laddering down. Then you need to follow the path of the garter stitch pattern with a new strand of yarn.
If you Google “garter stitch diagram” there are several diagrams that come up and they may help you to see the path of the yarn.
Thread a tapistry needle with the yarn strand and start several sts to the side of the hole and continue for several sts past the hole.
Once you’ve done this, weave in the ends and weave in the short ends from the original yarn.
