My grandson is a fan of Ninja Turtles. I decided to make him a Leonardo Ninja Turtle Scarf & a Raphael Ninja Turtle Hat. He was thrilled! I next made a Donatello Ear-Flaps Hat. Knitted flat. On 2 Needles. Intarsia. With a chart for the Ninja Turtle & written instructions too. It has ear-flaps & I-Cord straps to fasten it under the chin. This was also designed & knitted in a few hours in 1 day! It’s a quick –knit. It will delight anyone interested in Ninja Turtles. I increase my knowledge! Now Nani knows that the Blue mask is Leonardo, the red is Raphael, the orange is Michelangelo & the Purple is Donatello. So when my grandson told me, I said, yes, Nani knows a few things :D Last night I taught myself to knit an I-Cord seeing a YouTube video. It’s easy! :D For sizes 1-3years, 4 years, 5-6 years.
