Inkscape tutorial: fast grading from an existing pattern

How to grade an already existing pattern using this fast grading technique. This is by no means the "professional patternmakers" way of grading. But, for those of you at home with projector patterns, this will work reasonably well to grade up or down a size or two- not much more than that. This tutorial is a quick method to grade existing patterns up or down a size, or in between sizes, and is a rough estimate, rather than a 100% accurate method. This requires some basic Inkscape skill: My crash course to Inkscape for sewers is here: https://youtu.be/19d6M--7FrE Pattern I used is the Bridge Overalls sewing pattern from my Etsy shop: https://www.etsy.com/listing/887139395/harem-overall-dungaree-pdf-sewing?ref=shop_home_active_1
