Here's something I posted in 2009 - but I'm about to make some more of these so I thought I would publish this again.
Tiny Pointed Hats
"The little wooden blank dolls are from Winterwood but you can get loads on etsy from sellers such as Goose Greese Undone or Gemmielou. The head diameter of the ones I use is about 2cm.
I use 4 ply sock wool and I like using the variegated stuff (is that what a yarn buff would call it? the Patons stuff is called “Patonyle”) so that I get spontaneous stripes and patterns. My needles are size 2 3/4 (that’s 12 English size and 2 US size apparently!).
So; make a cup of tea, crack out the gingerbread, wield your long skinny needles and…
Cast on 20 stitches
Row 1: Knit 2, purl 2 and repeat until the end of the row
Repeat for two more rows to make the ribbing.
Next row: Knit row
Next row: Purl row
Next row: You will now begin to decrease to make the pointed hat. Knit 2 together and then knit to the end of the row.
Next row: Purl 2 together and then purl to the end of the row.
Repeat until you have one stitch left on your needle. Cast off.
Turn right sides together and sew sides together using row ends, leaving the bottom of the hat open. Turn inside out, using a chop stick or a knitting needle head to push the tip through. Embelish with sequins and beads or with simple embroidered details. Glue it to your little doll’s head.
(please use it for personal use and gifts only! Thanks folks)."
