This link leads you to a site with an excellent tutorial on how to “cut and sew” your knit yardage into a fashionable garment. The photos are excellent.
I have often used a sewing pattern to “knit to shape” garment using the Knit Contour device for the knitting machine, the mechanical KR7.
Larger items, such a jackets and coats, the cut and sew method is very useful for stabilizing the shoulders, neck and collar edges. I use it mostly for the necklines on lace and double-knit blanks.
Knitting your yardage, in your chosen colour and texture is what makes the project special.
