What paper did I use?
All the lovely samples I had seen in my blog travels had used SU 'Shimmery White' paper, which, alas, is not yet available in NZ/Aust. So, I decided to go with water colour paper instead. I am really happy with how it turned out, especially as this was my first (and only, so far) attempt at this technique. I might try glossy white card next. Anyone tried that already?
Did I use Water or Aqua painters?
Both! After you have heat embossed your image spray it with water until the water is pooling inside each of the embossed sections. This is a very 'wet' technique, which is why I decided to go with the water colour paper rather than ordinary card. I then used my aquapainter to 'pick up' ink (drops from a reinker) and deposit it in the appropriate part of the embossed image. The ink should spread thoughout each section by itself. If you want a bit more colour variation you can add more than one colour to each section, and laying the card on an angle to dry will result in a gradient of colour too. Be aware, your project will take a little while to dry.
