Felt telemark?

Has anyone felted knit picks telemarkyarn?
I want to use some for the eyes and nose on my huggable hedgehogs.
The hedgehogs are knit in ww yarn and the telemark I have is sport weight, will that make a difference?

I’ve never used any knit picks yarns, so no help there, I would just knit a test swatch and see what you think of it.

I don’t see why changing weight would be important unless you are concerned about messing up your guage…I make felted hats and ear warms with bulky handspun and cascade 220.

I don’t know why weight change would be an issue b/c I’m just going to embroider/sew the eyes and nose on before I felt so that they felt too.
