Germination

I have been trying to germinate alot of diffrent seeds but none of them seem to be sprouting and smell like rot. I am putting the seeds in between a wet paper towel in between 2 plates. I don't know if they are just bad seeds or what cus when I germinated before using this method they grew fine.

Should I use a diffrent germination technique or is it my water or something?

try soaking them in water for a day and they should crack, and whatever doesn't put into a humidity dome
