Is this rude to ask or am i bu?

Namechanged for this. I make costumes for the school I work at when the senior school do plays (private school). Quite a few of my friends know this.

Just been texted by a friend whose cousin works in a school about 10 miles away from mine saying that she's heard my school is doing the same play as her cousins only my school is doing it in march and her cousins school in June. Her cousin wants to know if she can borrow some of the costumes we use.

It is the junior school which are doing the play not the senior so nothing to do with me. I've never her cousin so I felt this was a bit of a weird/rude thing to ask. Friend knows how many hours I spend on these costumes and I don't get paid extra for making them on the side of my actual job at the school.

Am I just being over sensitive or does this seem really really cheeky?

Ah sorry OP I too was confused, I thought you had made them. I now see you did not make them and it is not your bit of the school.

Apologies. But you are still not being unreasonable, I even thought that when I thought you had made them!

Yanbu
I agree with steppemum and other posters who say that the borrowers might not look after the costumes etc.
Also if we are talking junior/seniors there's probably going to be alterations needed and there no guarantee they will be reversible,
Who will they get to do them.?
Obviously it's not up to the op but if I was being asked to lend these to a school that's not in my area / cluster that I had no contacts with, etc I would not be agreeing to it without an agreeing to a significant damages deposit or even a small payment and that's if I was minded to agree anyway.

I get what the OP is asking. Is it normal for friends to ask you if their cousin can borrow something from your workplace that you have no authority to lend/give.

Yes OP, your friend is cheeky to ask.

When I first read it I thought she meant the school friend was asking for was juniors asking for the seniors' costumes so don't worry, not the only one confused on first read. I think the man hours of work got distracting when actually there were no man outs of ops in these costumes.
