Day 7 was about creating the background and day 8 was about creating a soulmate self-portrait. The portrait was done on top of the background from the day before.
I learned a few things from this tutorial:
Use matt gel medium as a glue, it makes the pages buckle less.
Put a glaze over the top of the collage, paynes grey, white and mainly gel medium. This has the effect of toning down some of the colour and making the collage elements more connected.
Spritz white ink (I only had paint) over your collage, again, this makes the elements better connected.
