I am just putting a small piece of paper in a small plastic zip lock baggie , placing the seed inside with the paper and spraying a small amount water in, then placing it in the fridge. I lost some seeds to rot last year, and I am trying this method this year. I read where someone had used this with success.
I think the idea is to keep moisture in the enclosed environment and let the paper absorb the excess and prevent the seeds from sitting in water. It makes it easy to work with the seeds individually, we'll see how it goes.
