I decided to take a plunge and make the remaining big block. I decided that once the big blocks are out of the way, I will have a better idea of what fabrics I need to have left over for the remainder of the blocks. Here is the tutorial. The unfinished size of this block is 18.5 x 18.5. originally I wanted to put light blue in there instead of light blue, but when I started putting it together, it just didn't work! So I remade a quarter of "kite" blocks (which is no small feat), but I will say that I am very glad I did. I am quite happy with the result.
So I am done with 7 out of 18 blocks. 11 more to go, but the rest are smaller.
