Never under-estimate the task of removing the papers from paper-pieced blocks. Don't leave it until the end, if you can avoid it. I spent the entire season finale of "True Detective" removing the papers from just ten of the harlequin blocks. Just look at all that paper, and that's not even half of them! (And remember, I had removed the paper from all the center squares already.)
I needed to keep the papers in to do the inset seams, or I would have been taking them out all along, like I do with the paper-pieced Dear Jane blocks.
