I spent some time searching & didn't find much. Her last post on her FB page was 2017.
There is one kit on e-bay for "Quilts of a Different Color". The kit description reads:
"Included is a DVD on The Magic of Color Application, a book called Quilts of a Different Color, a DVD called Coloring with Pencils, Colored Pencils, Artists Brushes, a bottle of Delta Ceramcoat Textile Medium, a booklet called Stitch Your Quilt First add Color Later, and a little mixing cup. All you will need to create a beautiful masterpiece."
Other sellers on e-bay have just the book for sale. This is the only book I found still for sale.
Otherwise nothing. Her site link takes you to a page all written in some Asian language. Could be it got hacked & has not been fixed or redone since. Sites that had this same book as above for sale say sold out or not available. Looks like everything just stopped.
