When I have a ton of the same blocks to do, I do them assembly line. If I make just one then it's like, "been there, done that." I will make all the parts for all of the blocks at once. Each of 30 block needs 4 HSTs? Then I make 120 HSTs, just running them through one after another. Then move on to the next part of the blocks. At the end, I am assembling ALL of the blocks at the same time.
It keeps me moving on a quilt when I'm going onto the next part of the blocks all the time.
