I do it like my Dad did, squeeze the seeds onto a paper towel. Let dry and write the variety on the paper towel. When dry peel off the 2nd ply if there is one. Store in an envelope. I also cut off the excess paper. You can plant the paper towel as a layer or break off bits.
Thanks! Thats sort of how I do it. I also soak my seeds on paper towel and then plant them when they start to sprout.
