- PRINTED. Sewing patterns where construction pattern markings are printed directly onto each pattern piece conveniently for the sewer.
- PERFORATED. Sewing patterns where construction markings are symbolized by simple cutouts: triangles, squares and circles, for example.
When Ebenezer Butterick and his wife first invented sewing patterns they were crudely drawn onto stiff cardboard or whatever else was available.
As more and more pattern companies entered the market and competition increased pattern companies began coming up with new methods of attracting customers to their brand.
Pattern envelopes appeared and the information contained on them became more informative and helpful to the user. How-to information went from simplistic instructions on the envelope to detailed instruction sheets even the most basic of sewer could follow. Pattern perforations improved and eventually evolved into the printed word and included line drawings to indicate construction markings.
