The Diamond Hat
The Diamond Hat knitting pattern
Sometimes, knitting designs come quietly. I designed The Diamond Blanket pattern and felt that it needed a matching hat pattern. Thus, this Diamond hat pattern was born. There is something about these simple diamond stiches that are so eloquent!
I also designed a child cardigan to match this pattern as I fell in love with the design. This cardigan pattern is in the middle of testing. But, you can purchase the set The Simple Diamond Collection and get The Diamond Blanket, The Diamond Hat AND The Diamond Cardigan when it is released. Honestly, this set would be adorable for any little boy or girl!
As usual, my hat patterns come in many different sizes. This pattern has 10 sizes included from a NB size hat to an Adult Large.
The pattern is designed for a beanie hat, however, it is very simple to knit this hat in a slouch style. Directions are included in the pattern.
