These are two hats that I have just finished knitting for the homeless at St Mary's House of Welcome in Melbourne. I do quite a few hats and scarves over the year for them and also for a women's refuge that I support.
The blue hat was knitted in 2ply handspun, using white merino tops and then dyed. This hat has a garter stitch border at the bottom.
The multi coloured hat was knitted in 1 ply handspun merino tops which had been randomly dyed. Note the slant in the body of the hat ....... this is because I knitted the hat before I washed the handspun single .... this is called an "energised single". This hat was knitted on a circular needle and has a turned up brim.
