Pinwheel Sampler Quilt Along - Block Three

Here's my block three for the pinwheel sampler.  I LOVE the pink and yellow one.  That one is my all time favorite right now.

My additional block doesn't have much contrast to it.  Bummer but it will work.  And I want to know what is up with those threads!  I swear I clipped them off.  They multiply when you're not looking!

My favorite close-up...

Uh, does anybody else see the HUGE mistake in my block?!?!!?  I uploaded the pics last night and as I stare at them this morning... OMG.  Seam ripper, here I come!  I did the same thing on the other block but I caught the mistake yesterday afternoon before I put the block together....
Enjoy your day!
