My very favourite apron pattern is Mary Mulari's Church Lady Apron. It is reversible and easy to stitch, good instructions and fits well. It also looks great but it is not a free pattern. She also has several other vintage patterns for aprons and they are about $8.00 (here in Canada). I've made a lot of aprons and her patterns are the best by far. My apron using her pattern won viewer's choice in a apron challenge at our local quilt shop which had over forty entries.
