Sloper or Body Map? Two Tools for Better Fit They may look similar, but a sloper and a body map serve different purposes. Join Renee Bontjes of Sewing and Fitting Mentor for a special post-Frocktails demonstration exploring how a sloper supports pattern design, while a body map helps reveal the balance, proportions, and fitting needs of your unique shape. Whether you want to improve the fit of commercial patterns or begin exploring pattern design, this workshop will help you understand which tool is right for your sewing goals.
