I want to make pillowcases using Minkee with the dots and I am wondering if I can just serge the edges for the band or top of the pillowcase or should I turn it under and stitch? That probably does not make sense--sorry. If I fold the band 4 inches, should I fold it under about an inch and then stitch it down or just serge the edge and fold it dow 4 inches and sew? Also, I have seen them made with French seams but that seems to make a bulky seam. Could I just serge those seems too? Thank you in advance.
