yes - it's Tammie Bowser. I love her technique! I've made 4 photo quilts so far, and I'm working on another one right now. I think it's just the neatest thing. She's on Facebook, too - you can 'friend' her.
I won some of her software on a Facebook contest by having the most people 'like' my post about it. I love it!
You can just google
Tammie Bowser or Tammie Bowser Mosaic Quilt
and get to her.
Have fun with it!
