You could pick up the stitches on the front edges and knit a button band on one side and corresponding buttonholes on the other side. Use a stitch that will lie flat.
:drool: Oh, that’s so pretty! Great job. Love the colorway. As to buttons, I can’t help there. I still haven’t gotten brave enough to try a sweater. :verysad:
Mockle, that is BEAUTIFUL! Very well done! I’m envious. I will FOREVER be working on my first cardigan (and it isn’t even for me). I really like the pattern you used.
You did a great job on your first cardigan! The loops and toggles that folks are voting for sound like a good idea. They would go with the look of the sweater.
