Apron for Artists and Chefs Pattern The Apron for Artists and Chefs pattern was designed to help a beginner learn to sew successfully. For example, the side edges are on the straight of grain, not bias. The guide was written by teachers and tested by students over a two-year period. Make a toddler apron to match an adult’s – all sizes are included in the one pattern! Beginning sewing teachers—this pattern can be the basis of a series of classes. This pattern is used with the Learn to Sew With Janet Corzatt beginner’s sewing program.
