I took a bit of time for myself and finished up some pieces I had left unfinished in my sketch book. I had originally started these using watercolors and added detail with Pastel Sailor Pens then finished them up using a new favorite art supply Shiva's Oil Paintstiks. I've used water soluble pastels for years, but had never tried Shiva's Oil PaintStiks and I'm in love with them. They can be used on fabric, wood, metal and paper and are permanent. I highly recommend getting the blender stik to go with which ever set you choose. It helps with getting a smoother look. I like that I can dig in and just use my fingers to spread and manipulate the colors. The clean-up is great they wipe right off my hands with a paper towel and they don't dry out because they develop a skin that you just break through when your ready to use them again.
