Don't toss them! If you list them discounted due to needing repair, some sewing mama will probably snatch them up. From what I understand, replacing elastic isn't too difficult. If nothing else, you could donate them to somewhere like Miracle Diapers and I'm sure they'd be happy to have them. As far as contacting Jaime - you could just email her to let her know, as I think she would want to know if the materials she used didn't hold up very long. I'm not sure - maybe she'll offer to repair them? I know there are some WAHMs that will replace elastic for a small fee, too.
