Huh! Those do seem rather vague and not just allowing for creativity! At least it should tell your the finished size of the block. Did it have a layout pattern so you could see how many blocks across and rows down? That, with the total size of the quilt would allow you to do math to figure block size. But can understand your frustration! A poorly written pattern or kit really can be a big turn-off to quilting--I'd suggest you but it aside for that day that you want a big challenge and find one that you like. love Denise S' stuff but haven't used any of her patterns.
