Shannon from Little Kids Grow guest blogs in the Knock It Off series at Elegance & Elephants with a tutorial showing how to make this retro polo shirt for a little boy. The shirt is made from knit fabric, with woven fabric for the trim, collar, and placket. She had all the materials she needed in her stash, so this cost her nothing to make. Go to her tutorial.
