This beautiful block is Block #37, "Fixer Upper", of the Moda BlockHeads 3 Sew Along.  You can check the Moda website/blog for a complete archive of the blocks so far released in this sew-along.  There are some wonderful free patterns in four different block sizes, so you would be wise to at least download them for future reference if nothing else.

I do love the Square in a Square block, although it can be tricky to get right.  This pattern allows for just a smidge of trimming, which was mostly enough for my units to come out accurately.  It was fun to make, and the results are pretty striking.

I made one other block yesterday when I was trying to catch up on my BlockHeads progress.  This is block #36 "Broken Dishes". It was a truly unique block, due to its really unusual construction technique.  I didn't have my head completely wrapped around it, so my fabric choices were off.  I am going to re-do this block and show you all what I mean.  Here is what I accomplished yesterday.  It missed the mark due to a lack of contrast in the fabrics I selected, but I have a plan to rectify that with my second attempt.

Stay tuned.
