It's just that you don't have any idea of what the quilt will look like until you start putting the blocks together. Each month they send out new instructions for the next block, for example on this month we just cut fabric strips and then joined and subcut a set and they get put aside. Then the next month you work on the next clue (block) and as it progresses you need to start trying to figure out the answer to the mystery.
It's my first time doing this as well and so far I'm having fun! If you go to the designer's website there is an email address for her I'd send her an email and see if she'll send you the project sheets. I know a few others have asked that question as well.
