Help! How to repair thrifted sweater?

I recently thrifted a comfy sweater with the hopes of being able to repair some of the damage… only I have no idea where to begin !

Any tips, advice, or hints in the right direction would be greatly appreciated!
Have a great day :slight_smile:


Can you show the whole sweater? It almost looks like the pattern is made intentionally like that and it’s not actually damaged. Hard to tell because the color is dark.
