As a fellow blanketeer, our group pitches in to help our coordinator since we know we works so hard for the group. She brings donated fabric in on our meeting dates for the group to pick from. That helps keep her storage issues down. Not sure what she does with the non-usable fabrics but probably donates elsewhere.
A suggestion -- definitely try get a laundry to donate the machine so you can wash the fabrics.. Then bring the fabric (or at least some each month) to the group and have 1 or 2 people do the ironing. You definitely don't need to do everything yourself.
That's why YOU'RE the coordinator....
