Sewing on my block on the day of buck-a-block: not recommended. Too stressful. I don't do well with sewing deadlines.
However, I had done so much towards the block already that it came together rather quickly.
My block is on the left. Another version of the same block (using the actual fabrics provided to us) is on the right. I just loved seeing everyone's different ways to put together the same base pieces!
