I too have the collection (FW, DJ, PC and Sylvia) and they're all different. Dear Jane is difficult because there are no directions in the book. Some blocks have really tiny parts! I do have the DJ software to print the foundations or templates. Still you have to figure out yourself how to sew the blocks. There's a site (that quilt) where you can find directions how to sew the blocks.
The PC and FW have their own stories, they're great to read. Somehow I didn't like the PC blocks that much after all, I made a lot of them but not all. I started the FWS but only made about 30 blocks till now but I like them. My Sylvia is almost finished. Some blocks are very easy, some are not that easy but all directions are in the book.
