Two friends who have been quilting for decades were telling me their feelings about donating quilts for fundraisers.
They each made a quilt for a similar cause. One was raffled off, the other done as a silent auction is a high traffic better than mid price restaurant (the benefit was for a staff person).
The raffled quilt brought in more than $500.00, the silent auction quilt brought in around $70.00.
Where we live there are fairly strict rules around holding a raffle, where as a silent auction does not appear to be regulated.
I often see items at silent auctions going for 25 - 50% of their value.
