IF they appear to be in good condition, & not moldy or rotted, I say why not give it a try ??--be sure to dry them out well, so they dont mold in the mean time though. They should/could be kept in the gourd until it rattles, sorta like a maraca. But after they are dry in the gourd,
if you think you should look at them then do the newspaper thing:
Spread the seeds
on a layer of newspaper, and let them dry in a cool place for several weeks. When they are well dried, store them in a tightly sealed jar kept in a cool location. ( like say a refrigerator or a cool garage ) If you take a small cloth bag and fill with Powdered milk , tie it shut and place it in the same jar, it will absorb any extra moisture.
away from light or Moisture between collecting and planting. This will keep seeds
in a dormant state until you are ready/able to plant
Good luck & keep us informed...
