Well this is my first attempt with Prismacolor Premier pencils. They're oil based and you need a paint thinner to blend them. I didn't blend any colours, just kind of blended in the only colour, lol, but I'm liking them very much. They're lovely pencils to use, very smooth and glide perfectly. I'm using Sansodor artists paint thinner. Anyway, I think I did ok for the first go... well, apart from the face!!! LOL!
