First off, a previous answer to this question was "they didn't stupid" which is the most wrong answer I've seen on this site. Every American Indian culture (with two potential exceptions ) was stone age before Columbus, and they all had (at the very least, some) clothing. Not to mention the stone age cultures that are still around today.
To answer to your question - they made leather from animal skin, and used furs in colder areas. Stone age societies, especially paleolithic societies, don't have enough surplus of anything to waste a single thing; wasting something would usually result in you getting killed (though many times by your fellow tribesmen/clansmen who were pissed that you wasted something).
