Tents

What does it take to make a tent?

• cover from the weather
• tapestry or some form of wrapping around the outside to protect from wind.
• something to keep it to surface without wind blowing it away.
• optional windows for seeing and allowing air in.
• plenty of room to spread out.
• a way to close the doors and windows

I really can't think of anything else except that it needs to be put up easily and taken down easily.
