I designed and knit a traditional style woollen socks with the traditional style heel in toddler size. I used hand dyed no logo 100% merino wool which I received as a gift from a friend.
Notice that this heel is exactly the basic plain & original Dutch Heel. This is not as durable as Dutch Heel No 1 (trad.), Dutch Heel No2 (var.) and Dutch Heel No3 (var.).
The heel is made:
every 2nd row - knit
every 2nd row - purl
always slip the 1st stitch
