Why buy stuff you don't need and can't use now? I have been visiting local LQS as I travel, and sometimes I feel obligated to buy something. After a visit to one store in LA, I now have FQ in what I was told was official New Orleans colors (Purple, bright green, gold trefoils, and black) and high-quality but dreadful-baby-print corduroys , most of which I will have to buy $100 of fabric to complement it and make something out of it, if I live long enough. Lesson learned.
Now I only buy sensible blenders or a brilliant pattern or a great pair of scissors or a special ruler or thread.
My advice is don't buy it unless you need it or you love it - and if you love it (like another poster said) go crazy! buy yards, because you will find it won't be around later. Fabric designs are produced in limited quantities and often sell out quickly.
