Each pack comes in a simple A4 folder, containing five (six if you're one of the first 100 orders) A3 sized colouring pages folded in half. The paper is a very thick cardstock suitable for using wet media as well as having a good tooth for pencil layering.
The Flow illustrations are most similar to Secrets, in that they are centred around couples and the human form, frolicking sensually among flowers and foliage. The pictures contain masses of leaves and florals, the hidden images not always immediately apparent until you're close to completing the picture.
Here are my finished pictures from Flow and Goth, which I had lots of fun colouring with a whole plethora of marker brands. I'll be keeping my eye out for the new book from Vivid Owl and let you all know when I find out anything!
