Efficient cutting and preparation of fabric for sewing clothing
I would hesitate to cut my fabric into smaller pieces for storage, just because I can pretty much guarantee that as soon as you cut your fabric, the universe will send you the perfect pattern for that particular piece of fabric--but the pattern will require about 1/2 yard longer than your chosen cutting length. 

But the reason I wanted to post an answer is because I just took a sewing class where my instructor insisted on teaching us how to cut fabric when you only have a small cutting surface.  The basic tenets were that you should NEVER let fabric hang over the edge of the table, as this can pull parts of your fabric off grain.  Instead we spent a lot of time folding and refolding unused and/or already pinned sections of fabric as we laid out our patterns in preparation for cutting.
