I totally agree with jumping in to help. Our guild has a quilt show in even numbered years. There are so many tasks that need to be done - many of which don't take much time, but the sheer number means that a small group can't do them (for instance - sitting at the table for 2 hours during the show selling tickets, or helping hang the show or take-down). Gus and I have helped with take-down the past 2 shows and this helped me learn lots of member names.
For that last show, I took a day off work to help with the judging and spent the day as a Scribe for the judge - writing comments as fast as I could (there were four of us scribing for her so I learned a lot about every fourth quilt...). That was a fantastic learning experience as well as getting to know other guild members during the day.
I now share Hospitality duties with another member - I coordinate the Summer Ice Cream Social and she coordinates the Winter Potluck. It works well for the two of us.
Cheers, K
