3D quilt block

Block 3 in the Quick as a Fox sewalong is a 3D Block:

Where is this 3rd dimension, you ask? See those lime green triangles? They're actually folded over squares, sewn over top of another square, thus forming a pocket of sorts.

Pretty cool, huh?

I liked seeing this block come to life, but I'm glad it's a sampler quilt and I don't have to make another - so many seams, so much pressing!

It's still pretty cool though.
