Fabric recommendations: Only use stretch knit fabrics, such as ribbed cotton or viscose jersey, cut-and-sew knit fabric, or stretch Milano knit. Knit fabrics can be assembled either with the sewing machine or if you have one, an overlocker. Choose a special jersey needle with a rounded point that will not damage the fabric and make sewing easier. Select the elastic stitch on your machine. On the overlocker, adapt the differential feed in order to have elasticity in the assembly seam.
