Dear Prudence,
My family is big into Renaissance fairs, and I hand-sew all our costumes. Our girls have outgrown a few of them, so my sister-in-law asked if she could borrow them for Halloween. I agreed if she promised to take care of them and return them clean. My niece took the first one for her school trick-or-treat festival. My sister-in-law returned the dress completely trashed, with the fabric ruined and the embroidery pulled out: She threw the dress in with her laundry, rather than getting it dry-cleaned like I requested. No apology, just the excuse that it was “shoddy work.” I refused to give her the other items, and she yelled that I was breaking my promise and “ruining Halloween.” My husband agrees his sister is out of line but wants me to put it aside for the sake of family harmony. I spent hours of work on these clothes and don’t understand how I got to be the bad guy. What do I do?
