That's a great find. My friend get some fabulous fabrics from Goodwill. Unfortunately I'm allergic to the smell of goodwill shops. Sets off my hayfever and sinus. I'm lucky that my friend will sometime share her finds with me after she has laundered them.
She gave me some great fabric with balloons which made a fabulous border for an I Spy which I gave to K Mart's Wishing Tree last Christmas.
