I have self-published two free patterns, simple quick patterns. I'm currently working on 2 different patterns, a bit more complex than these. I expect to have them ready to publish before the end of this year, but I may try to submit them to online sites for publication.
The Aztec hat was made for my husband who had asked for a cabled hat with no brim. This is what I designed, it was my 2nd choice in yarn and swatch.

The Skull Cowl pattern came about me needing something to wear while Trick'O'Treating with my kids. The white skulls are made with glow in the dark yarn, which was a pretty cool touch.
