I would either leave the quilt there and NEVER ever make something for them again.
Or i would take the quilt with me home and repair it if and when you fancy doing so but i would still not never make anything for ppl that are so careless like they seem to be.
When you get something you know someone has spent a long time making for you the least thing you do is to take care of it.
I d be furious with him if i was you, actually i d be tempted to kill him and give him a extremely good seeing too.
Do not let ppl treat you and ur crafts like this, you are way too good for that.
Sending you loads of hugs
