Banana, I think that sounds great if you're up for it! I would volunteer, but I'll be on limited availability for the next 10 days or so. I wouldn't be able to do much until early August... and I agree that getting started sooner than later is a good idea!
Sounds like there's a good concensus that a $15-20 limit (coordinator can pick one or the other) is reasonable, and that requests or donations for handmade items are great. Handmade items should just be valued at the $15-20 mark, I think, though obviously that's sometimes hard to pin point. I like some of the questions from the August board - I'm sure it made it easier to match people knowing what types of things the mama could/would provide, and what type they would like to receive.
I think on my old Sept '04 DDC, we made our lists and then were able to tell the coordinator a few people we could provide for. She then matched everyone up and put up the list. I think either of those methods could work well.
