One option; Very very carefully take the seed in between your pointer finger and thumb and manipulate it in a way where if you apple pressure the seam where the seed will naturally begin to open at you can forcefully (but gently and kindly and not crazylike) open it with a tiny tiny amount of pressure. You feel a 'snap' and that's it, don't open further, back into medium/paper towel etc. Good luck, sometimes works sometimes not.
Just to give some idea of a picture of what this looks like, for me, the pointiest end of the seed will be exposed at the end of my finger and thumb, when i feel that 'snap' I can see that point having opened while pressure still applied, without pressure sometimes it closes back up but you know it cracked and the little gal can begin life.
