My plan was to do a knitted i-cord seam to connect the border to the center field of Grandma’s blanket. Before delving in, I made a swatch of stockinette stitch and tried out the seam method by joining the sides of the test fabric. I’m glad I tried it on scrap yarn first. I don’t like it at all. The seam ends up thick and bulky and not very elastic.

So I guess I will sew the seams. I don’t mind sewing, so it isn’t a hardship, but matching up everything can be quite daunting.
