A few weeks ago I put a notice in my parish bulletin offering free rosary repair. I've had more than a few parishioners take me up on my offer and all have had their rosaries repaired and back in working order. I'm happy to do it, just to know someone is able to pray their rosary again. Several people said they tried to find someone to fix it, but had no luck.
I'm sending out the same offer here. If you have a rosary with broken links or chain, I will repair it for free -- just the cost of shipping. If you are missing beads, I can try to find a replacement and will fix it at cost. Just send me an e-mail.
