here’s a great way to fix it, with zero sewing involved, which is fabulous- especially if you’re a lousy seamstress (like i am!). here’s how to do it:
get some iron on appliques in the size of the tear and iron one side one. Let it set into the fabric. Then pull it tightly and fold over the tear, iron the other side on.
If you need to you can pin it in place prior to ironing so you can use both hands to iron.
