Child's Self-striping Hat
I’ve revised my notes (7/1/2016) to provide additional guidance regarding the ages that correspond to the cast on numbers:
Head Circumference Size Guides:
Craft Yarn Council - Basic guide - if you download the PDF and want to print the portion that contains the chart, print page 9. Additional baby/child size charts are on page 6.
The actual difference between the finished size of a Hat compared to the desired size is usually 2in/5cm or 12%, - this is the normal amount of negative ease included within Woolly Wormhead knitted and crocheted Hat patterns.
- Bev’s Country Cottage - Pretty much everything you need to know if you knit knit hats for babies/children. On Ravelry, you can find her patterns here. Quoted below, emphasis mine.
Head/hat Size Chart - knitted or crocheted hats should be made about 1- 1 1/2” smaller around than the head circumference, as the hats should stretch and sizes are not an exact science! If you make it, someone will fit into it.
Knit a swatch hat by casting on for the smallest size, bearing in mind that the smallest size might have to be knit on DPNs (or Magic Loop or Two Circulars). For me, 72 stitches requires DPNs - it’s my preference. Because I typically do not like to knit baby hats on anything other than sport/DK, this means if I’m casting on 72 stitches, the hat will fit a newborn.
Using the guidelines from the Craft Yarn Council, on their Head Circumference Chart, here is a way to determine what your finished hat might measure:
Baby - 14” circumference means the finished hat might measure between 12” to 13” in circumference
Toddler - 16” circumference means the finished hat might measure between 14” to 15” in circumference
Child - 18” circumference means the finished hat might measure between 16” - 17” in circumference
