Since I've been working on my altered book for the past couple of months, I have been leaning towards using materials that won't allow the pages to stick together. Some of them are matte or craft acrylic paints, acrylic gouache, watercolour, pen & ink and now also a few Faber-Castell pencil crayons. I have also always drawn out my wardrobe for packing in my journal, so these have been so much fun to use there as well. I did end up picking up a few more colours, lime green, grey and black as I prefer to draw with something that doesn't smudge (like pencil or charcoal)...I'm okay with sketching new lines and doodling rather than being able to erase as I think those marks make the drawings much more interesting for me. Anyway, having fun with these for now...I may add a few Derwent Inktense as well as I've been hearing so many good things about them.
