It's never a problem to ask questions. :D I'm glad you found your answer.
With this block scaling down is quite easy, you can just take your square up rule that you use for cutting your blocks to side, and go around placing lids, plates etc, within the area that you'd like. Or just cut the block size you want and stack circles of different sizes until you find the circle sizes you'd like. Just don't forget to leave space on the sides for the seam allowances.
