Leather scraps?

[purgatori84.livejournal.com]

I'm looking to start playing around with leather, and was wondering if anyone knew of anywhere to get a heap of leather scraps locally (or at least within the Boston metro area). I know I can get old leather goods at goodwill, but I'd prefer to have a little more variety in color and thickness than I could get with one old jacket. Free or cheap is definitely a plus.

Thanks!
