I've done a little reverse applique, but it seemed so much more long winded and complicated compared to regular applique, and I still can't quite see the point. I've only done a little colouring too. That was with a quilt kit I bought from Australia. They supplied colouring pencils which I used to fill in some areas I had embroidered. I was pleased with the effect, but I have never seen the pencils for sale anywhere else, so came to a halt after that.
