My first option would be to tell myself, since this is new, it's going to be available for a long time. Then I would go home and find pictures of it on-line and save them to my 'would like to buy' folder, and see if I still felt the same way in a few weeks. Sometimes the infatuation is short-lived.
I've never had the budget to by 4 or even 2 yards of an entire fabric line! If I wanted the whole line, I'd probably go the FQ or F8th bundle route. Or, I'd go and search out a particular pattern for it, and then I would know exactly how much of what fabric to buy.
