The Many Blocks of March

This is my continuing monthly count of blocks made for for Prairie Moon Quilts' 350 Block Challenge.  Here's the list of the 130 blocks made in March. Added to the 49 blocks made in January and February, the new running total for 2016 is 179.

I made six Violet blocks for the Block Lotto. You can find the free pattern here.
Four more for my rainbow sampler
And eleven more for my Old MacDonalds Mystery Sampler (AKA OMMS)
I couldn't resist playing with all the bonus half-square triangle units that resulted from the violets, so I made 18 tiny pinwheels ...
Then used 17 of the pinwheels as one of the "fabrics" to make these eight improv pieced floating squares blocks–chunks really–which became Floating Pinwheels.
I used the rest of the tiny bonus triangle squares in these nine Clover Blossom blocks
I added these four scrappy blocks (and a whole bunch more HST units, made for the border) to complete the little quilt top
I made this block for the "Everything Old is New Again" challenge
Then played with the design a little and hand-pieced these four Wavy Gravy blocks
I pieced a bunch of letter blocks, including these nine (for a secret project)
And this complete subliminal alphabet (25 blocks), sewed it together and added borders–it's also ready to quilt.
While adding borders to some almost ready-to-quilt projects, a very old UFO caught my eye and I added 29 new Summer Vine blocks to the pile of 35 blocks made in 2002, for a total so far of 64 blocks.
And although I am a little behind on keeping ahead of the Block Lotto, I made two of these foundation pieced Butterfly blocks. The block pattern for this paper pieced block (with tips for creating paper-pieced blocks with on-grain edges (to avoid those stretchy biases) is here: Butterfly
