The pattern is available in Norwegian and English, and it contains written text and chart.
The hat is knitted bottom up, starting with rib.
It’s not that the motif of a tractor does not exist already, because it does. It’s more the challenge. Would you be able to make your own version of the motif?
That’s how this design started. And a tractor is interesting. Big wheels and small wheels. Windows and a pipe. And it all will have to fit into a chart. And the chart must be small enough to be placed on a hat. And the hat must have the right size for a kid. Or not really, but the first sample was made to a little boy who just loved vehicles.
A fun challenge indeed!
