Answer: Wash the pulp off the seeds, then dry them thoroughly (several weeks at room temperature). Label them and pack them in an airtight container such as a sealed jar and place this in the refrigerator (or anywhere the temperature is cool and constant). Keep in mind, though, that the seeds you've saved may not produce pumpkins as nice as the ones you grew this year. This is especially possible if you saved seed from a hybrid pumpkin or if you grew squash near the pumpkins since these may cross pollinate.
