What is the craziest bit of piecing that you have ever done?

Mine has to be this! 276 pieces in 36 square inches when finished, equivalent of a 6″x6″ block. I have worked on it for well over 20 hours now, including the drafting, printing, ironing, cutting, sewing, ironing, sewing, ironing, sewing – you know the drill! I am still to remove all the paper.
Do check in to see what I have been up to! I get back to removing paper from each of those 1/4″ strips you see in the picture ( the remaining four pieces are huge 1″ squares!
Happy quilting to you!
P.S. You can see what I did with all that piecing here.
