Many years ago I donated a quilt that I made to an org. that my husband belonged to, they were restoring an old meeting hall. This was back in the mid eighties when quilts were not so readily available at the local Walmart,Target etc. and a hand made quilt was more of a novelty. The tickets were sold as a raffle, and the org. made a little over $1,000. I was quite proud of that. This was an historical reenacting group, so I made star blocks in red,white and blue.
It is true in making a raffle quilt or one to sell, as previously said, what would the general public of your area like? and too, queen size goes over the best. Good idea about throw and kids quilts also.
