I have added "techno" buttons with what look like little screw heads to give it a more masculine touch.
I had a little problem with the collar. The instructions are to knit the collar separately and to then sew it on. This is a bit tricky as there are live stitches along the back neck edge and the collar must be stretched to fit and to roll nicely. I'm glad I have experience in sewing to know how to make the collar fit properly. Also I questioned just how to sew the collar on to make a nice seam edge on the inside. I probably should have done a little research on technique, but I was in a big hurry to finish the sweater. Yeah!!!!! It is done.
