I have no purple so I can't help you, but I did want to mention a store just found that has great prices, great selection and quick shipping. I haven't actually gotten my first order in the mail yet so I can't attest to the look once it arrives, but even if it's all scrunched up in the box, I'd be happy because the prices were very good!!

I have also gotten from Fabric.com and I like them and their prices too, but the place I linked above has comparable prices to them (cheaper with quantity discounts actually), and now that Fabric.com is owned by Amazon, I enjoy supporting the little guys more (when it comes to fabric anyway), so I liked working with Hawthorne for that reason.
Best of luck!!
