Oh My, I just finished "sglk'segtjso" Pharlemia and what a brain teaser she was!!!!
I found that by sewing just the center seams of the outside sections all aroung all I had to do was to sew just the sides it should work out..and it did but with much frustations because the center seams had to be matched perfectly with the side..I had to rip out several of them and re pin, smack down, fold over..the last time I was this frustrated was with a Bird bloc from the first FWS..There is one almost the same in the 90's of this FWS..
Here's Pharlemia...I think when the paper comes off it will lay alot flatterand less twisted in one or two areas..
