It does look like a font, rather than lettering, due to the repeat letters (K, N, etc.).

I have no idea what typeface this is. Just wanted to say how much I like the work of Nikki McClure.

Here’s the rest of this calendar, in case it helps others to identify the font.

Hmmm… maybe it’s her own design. It does fit the cut paper aesthetic quite nicely.

Josh... Your last comment inspired me to search Google by typing “nikki mcclure font”... It brought up an interview in which she is asked,

And what are your thoughts on digital art?

Her response:

Digital art? go for it. I use computer to make the printed versions of my pictures...but I also use handcut text in a font that we made. I want it to be handmade without computer text as much as possible. Just like in nature how nothing is perfect. There are always holes in leaves, torn edges, no solid color. It is getting harder to see these things. [Bold highlighting is mine.]

:-) I suppose she is talking about the font in the image you posted.

The full interview is here.

Thanks for tracking that down Ricardo.
Her work is very beautiful and it was very smart of her to create a custom typeface for it. In addition to tying in with nature and the subjects of her art, the imperfections in the cut paper letters add a level of warmth that a traditional geometric sans could not achieve.
Too bad it’s not available. Its very sweet.
