Summarize the following:
Find a location where there is no danger of dampness. An indoor location like a shed or hayloft or shaded outdoor region works. Avoid areas with little airflow, such as garages, and never dry them in a basement.  Check your drying pumpkin seeds daily and turn them so they dry evenly on both sides. Do not leave your seeds in clumps. They will not dry thoroughly and this might cause mold to develop. Air-drying is the most effective and safest method of drying, but also the most time-consuming. Pour all of your seeds in an envelope or paper bag and store them somewhere cool and dry. If you can't find a suitable location, place in them in the refrigerator. Discard any seeds with mold and mildew.

Summary:
Air-dry your seeds in a cool, dry place for at least 1 month. Store your dried seeds in a paper bag or envelope until roasting or planting.
