Birch versus Fir ~ What would be the difference in a craft?

Question

I'm trying to copy a craft I saw today. They used 2" birch cubes to make a puzzle. The only 2" cubes I could find on the Internet were made of fir. Knowing nothing about wood, I don't know if that would make a big difference? Would anyone out there know? Thanks!

Answer 1

Birch is a white wood, fir tends to be tan or light brown. Birch will have a straight grain, fir will have a tough winter grain with soft summer grain, and can be meandering or uneven.

I think the fir blocks will work for your craft, even though birch is categorized as a "hardwood," it is softer than the fir.
