Morse Code or Braille monogram
It occurred to me today that it would be quite easy to knit or crochet a child's initial or name in Morse Code or Braille on the front or back of a sweater. Never thought of that before. I think I would make the Morse Code dots and dashes in purl stitches against a knit side of the stockinette pattern. In crochet, you could play around with clusters or popcorn stitch. I guess you could knit popcorn stitches for dots too. Anyone ever done this?
