Simple Diamond Hat Knitting Pattern

This simple diamond hat knitting pattern is so much fun to knit and makes a great baby shower gift for newborns, babies and toddlers!

I am so in love with this simple diamond hat. It kind of reminds me of a great pair of socks (I love socks, so to me that’s a positive thing, ha! )

And of course, because I’m predictable, I knit this fair isle baby hat pattern up in a light teal and dark teal. I think I have a teal problem! I might have to make another one in another set of colors though, just because I know it will look equally as fabulous!

This hat would also look adorable with a pom pom on top, although I left it off mine just as a change of pace. But you could make the pom pom in either of the diamond colors or even in a third color for a little pop! That would be so cute!

As an aside, I tend to give Baby V random things to play with when I take photos, to keep her happy, and look at the pic below, totally unplanned, I handed her a big fake diamond! For the Simple Diamond hat!

I didn’t even notice until I was editing the photos. I love it when things work out like that!
