I am relieved to see I was not the only one who struggled with this block. I almost had to ask for replacement fabric from the QB too, and since they're vintage sheets I didn't even know if it was possible! Luckily my cutting errors were salvageable... at first I cut the wrong print for the center, but then luckily it turned out that I had to cut that fabric to the same size as the center piece anyway. BIG "phew" moment there.
Then as I was squaring up a green 5" piece to cut 2 1/2" squares from (to make the HSTs), I accidentally cut one side to 4 3/4"... d'oh!! I was able to fudge the 4 less-than-perfect HSTs in the block, and hopefully Kim will be able to fudge the 4 corresponding mini ones for her sawtooth border. ;)

I couldn't find a good spot in my apartment to photograph this but liked how it looked in the window!

Here's a "normal" picture of it...

Leftover mini-HSTs for sawtooth border as requested

Okay... Whew.  I wonder if someone told Kim W. that I am the worst at precision piecing, unless it is on a foundation.  So my ordeal began when I used the wrong square for one of the parts.  Now mind you, normally it would be an oops okay, but I had the precise number of pieces and they were all VINTAGE..
