Could it be from the pet series back in the late 90's? Sorry I don't know for sure but I bet someone will come along soon who does. You sure have enough there for a large quilt back. Good for you!!
Back in 1998 I refurbished a motor home from top to bottom in Debbie Mumm fabrics. Curtains, seat cushions, linens... everything I could put fabric to. I loved the angel prints way back when ;)
