Hi Jaba,
This fabric is from the Nature's Elements collection, it shows
www.artgalleryfabrics.com, I bought it from a quilt shop that has closed about 4 months ago. But it comes in all kinds of beautiful colors. All the colors are perfect for Boomerang since the design is not overwhelming, but give us the colors we need to coordinate with everyones fabric. You may be able to find that design on ebay or the site will show shops that carry that brand.
Thanks,
Ruth
