Have you ever been lucky enough to inherit sewing supplies, or find them at a yard or estate sale?  No doubt there can be amazing vintage finds including sewing machines that will easily glide through multiple layers without a groan, vintage dress forms and out of print patterns, mysterious sewing objects from the golden years, and sometimes huge collections of vintage fabrics and threads.
