Have you discovered this fabulous online shop yet? It's called Thousands of Bolts and they have an amazing inventory of fabric at blowout prices. TONS of Moda fabrics - my favorite. Fabrics are arranged on pages by color or theme, or you can click the search button and look for fabrics by manufacturer like Moda or Timeless Treasures, or search by the name of a specific fabric collection.
I bought these cool prints from Moda's Nell's Flower Shop line for a mere $4.15 a yard - is that incredible? I have plenty for borders and backing and a background at a price that was too good to pass up.
You do have to buy a yard at a time, but at these prices, wow - build the stash a little! Check them out, they might have the perfect back or borders for your quilt and you could save some money too!
