I first came across this fab idea when I saw Ellen Vargo demonstrate it on you tube. I've added a few pieces of T!m's tissue tape to a piece of heavy weight card.
I then brayered on pyrrole orange Decoart media acrylic paint.
Then a splash of hansa yellow.
Followed by primary magenta.
And finally napthol red.
Then I used carbon black and titanium white to add some interest using various sized lids and an old phone card.
All the paints are from DecoArts media range.
