This little chef set makes play time even more fun. This hat and apron are knit with a worsted weight yarn that gauges at 4 stitches per inch and a US #9 needle. There are ties around the neck and back and can be worn by your little one while playing in the kitchen, creating art, playing with dolls and so much more. The pattern fits ages 3-10 years. The hat has a circumference of 19-20” and is slightly adjustable. The hardest part is deciding which color to knit it in first!
