This is a vest I made for my son-Lukas. I used knitpick dye yourself merrino yarn. I dye them with 2 different shades of blue. I just measure my gaguge, and start to knit this one. No pattern--I like kids wear simple stuff. This one use almost 1 skein( 440yard). It is a little big for him right now, but I think it will be just fine in winter. I dyed the yarn with the lighter blue first. Then I made few node on the skein, then dye it in darker blue again. I think I want to make (dye) darker color next time.
