I have put together a list of SOME of my supplies. I use many different supplies and brands. This is just a sample for you. I will keep adding to this list.
Bubble wrap, shelf liner, old credit card, toilet paper roll (other random mixed media texture tools)
Canvas (I order in bulk at Dick Blick)
Caran d Ache water soluble crayon
Gesso (white and clear) I prefer matte
Masking tape
Raw Umber glaze
Stabilo marks all pencils (black and grey)
Watercolor Paper (I like 140lb hot hot press or cold press. Hot for less texture and cold for more)
Workable Fixative (be aware that this can change the coloring of your piece)
