I assigned each person a "raffle number" based on the order they contributed to the fundraiser.
#1 Hong P. of Secret Garden Studios
#2 Priya of Live to Cook
#3 Canine Cologne of Pink Candles at Ridgemont High
I used Random.org's random sequence generator.
And here's the order Random.org selected of who won 1st, 2nd, 3rd place.
