Small mesh burn… help!

Hi all, I'm hoping someone might have a good fix for small mesh melt/ burn from a hot tool. I'm rhinestoning a seam where it's mesh over fabric and the hot tool got too close to the body of the costume. I'm mostly worried about it running or getting bigger. I'm hoping someone might have a good suggestion for this. The area is mesh over fabric so I can use a patch under. This is her second comp year and my first time doing rhinestones...
