Technique falls under patent law, not copyright, and it has to be new, unique, involve an inventive step, and have industrial applications. Patents last only 20 years and are not renewable. Copyright only covers the written/photographed/taped description of a technique, not the technique itself.
I strongly doubt that fractured quilts qualify for a patent so I'd say, if you use your own words, you're safe to share it if asked...not sure I'd want to start giving classes, however...but that's just my 'educated' opinion.
