In my experience paper towel releases small dust like particles and disintegrates easily while scraping the seeds, in my opinion it adds extra vectors of contamination. I prefer to use smooth surface paper, like lenses paper or filter paper.
What I find most complicated about orchid seed storage is that the ideal conditions vary so much regarding each specie. I read Phaleanopsis last maximum 6 months whatever method you use to store them....
