If you are saving lots of different seeds, several envelopes can fit inside one, quart-sized jar. It's also a good idea to put a tablespoon of dry rice at the bottom of the jar just to absorb any moisture. You can also save butternut squash seeds by using a food dehydrator. Spread the seeds out in a single layer on the dehydrator tray.
Depending on the model, you may need to put the seeds on foil so they don't fall through the trays. Drying times vary depending on the dehydrator model, but the seeds are usually dry enough in a day or two.
The key is to use the lowest available setting and keep the seeds as far away from the heat source as possible. A third option for saving butternut squash seeds is just letting them air dry. Spread them in a single layer on a baking sheet or foil and put them in a dry place, preferably away from the humidity of a kitchen.

When working with varieties whose seeds are hard to separate from the pulp, soaking the seeds for a few hours can facilitate cleaning.
Large screens made from quarter-inch hardware cloth work well for cleaning and rinsing big batches of seeds. Immediately after cleaning, rinsed seeds should be spread out to dry in a thin layer on screens, if possible. Decanting can be a good way to separate viable seeds from lightweight and underdeveloped seeds.
Decanting simply means pouring out the mixture of water, pulp, and immature seeds off the top of the liquid, while keeping the mature, viable seeds at the bottom of the glass. This method is only effective for some types of squash because even the viable seeds of many varieties will float, rather than sink.
Alternatively, winnowing can help separate lightweight and underdeveloped seeds once the seeds are dry. When fruits are processed individually - such as when winter squash seeds are extracted as a meal is prepared - the seeds should be cleaned and then mixed in and stored with seeds of other fruits from the same planting, in order to maintain the genetic diversity of the seed crop.

Plant butternut seeds outdoors in late spring to early summer, only after daytime temperatures are predictably above 75 degrees Fahrenheit.
