Yes, those four pink squares are what prevented me from finishing this block yesterday!
And, although this picture looks like a block that you could call finished, it isn't.
The plaid fabric indicates that this is one of the corner blocks.
I actually like the way this looks, but since it is not yet a block...
We add pink triangles. It kind of looks like I might have tried too hard not to cut off the corners of the pink squares! Ah, well!
And now, I really have 10 of the 12 blocks completed!
