I believe the fabric could be either called Lamour by Sandy Gervais for Moda Fabrics. There are probably 12-15 different heart fabrics in that line. The other is by Loralie Harris it was made for breast cancer awarenss. It definitely has the curly tops but not sure who the manufacturer is I can't recall. Both are high end quilt fabrics. You can go to United Notions.com for the Moda fabrics. I use a wholesaler that has a link to other fabric manufacturers that may help. It is www.fousttextiles.com/links/
I use it when I need a special fabric they can order for me. Hope this helps. Good Luck!

I always use the search engine at www.quiltshops.com

They will show you thumbnails of every fabric in hundreds of quilt shops that meet your search criteria. You can buy it from the shop that has it, usually there are several shops that have it.

This link is to the L'Amour fabric that graciesfire found.
