Prepper reasons
Your house will never float down the river with your stash and 2 dozens sewing machines.
When the power goes out you can wrap the whole family and pets in layers of fabric to keep them warm.
If you shelter in place you have enough fabric to block airflow in all the rooms.
If you need heat you could (gasp) burn your fabric and sewing machine tables to keep warm.
If you have a fire and the rest of the house burns, you can still cover the family.
You can set trip alarms all through your property with thread.
You can float down a river with tubs tied together.
