The quilt is yours to use as you please. If the quilting group that made the quilt wishes to control the fate of the quilt, they should not be raffling quilts. I'm sure that many people who buy raffle tickets do it for a good deed to benefit the sellers , not necessarily because they love the quilt. Are they obligated to use the quilt on their bed? Do as you wish and blessings on whatever you decide to do!
