Hi Tina,
I have found The Fabric Guild to be great for fillers and background fabrics. All are 100% good quality cotton. Ring them up if you can't see what you want online. They're really helpful. I now get most of my fabrics from there or from the two shows a year that I attend. It takes some planning but it works for me. I use Modabakeshop patterns a lot too.
Hope you haven't had a bad time with the floods in your region.
Annie
