Blockheads 4 Update - Some Finished Blocks

I'm working on Little Blocks 4.5 and the 4.5 inch blocks in Blockheads 4 simultaneously but progress slowed when first, I injured my right index finger (not a rotary cutter accident but the finger hurt making using a rotary cutter difficult) and then I got Covid-19 (a very mild case, like a cold).  I've recovered, and so has my finger, and I'm caught up on Blockheads 4 blocks.

So here are five of the first six blocks.  I chose not to make one (Block 3?) because it had too many pieces for me to manage in the small size.  However, I may go back and make it later.  These blocks are good practice for piecing accuracy and as mine improves, I am more confident in my ability to manage the tiny pieces.  The biggest challenge is the build-up of seam allowances on the back.  

I'm using fabric from my stash for this project, a mix of red and green Christmas prints and assorted backgrounds.  I'm not sure yet what setting I'll use; I had a couple of ideas at the start but I've seen some interesting settings from other participants so am undecided now.
