{Post 1,421} Disappearing Blocks

I backed a baby quilt with this baby blue fabric.  I don't even know how long it's been languishing in my stash, but it will soon be completely gone.  

Have you seen the disappearing hourglass blocks?  You go from picture 1 to picture 2 in just a few easy steps.  I plan to make a shirt quilt from this pattern with muslin.  I was inspired by my friend, Janet.  See her post here.

I have enough scraps for 4 blocks plus a few strings.  I am going to use it all up for this!  I think I'll make 2 of the disappearing pinwheels, too, just for sake of trying them out.  So I'll have 4 12-inch blocks...two of each kind.
