This is what I do - it works for me. Here is a sample I did with the Prisma pencils and I used mineral spirits.

1.) Soak your stump - I'm not talking hours here - just enough for the liquid to go up the stump about a third of the way.
2.) While it is soaking, stamp your image using PERMANENT ink. SU basic black or Stazon. Make sure the ink is completely dry - even if you think it's dry, give it another minute or two.
3.) Pick out your pencil colors
4.) Put ONE mark on your paper with ONE color only, where you want it the darkest. You will blend off of that one line.
5.) Take your stump out, and blot it once or twice. It shouldn't be dry, but nothing dripping off of it either.
6.) Start pulling with your stump in a circular motion off the line of color you made. If you have blended it too much, make another line in the place of your original line, and go from there.
Blending takes patience. The card shown was one I sent to my Stamp Camps attendees. I sent each person one of them. By the last card I made, I felt more comfortable with the blending process and how much pencil I had to lay down in each area to get the look I was going for. There are so many variables when it comes to doing this, that these are not hard set rules. If it's a hot day, your pencils will run more smoothly, and it may not take as much pencil to paper. A lot also depends on how much liquid your stump has taken in. When you do it for a while, just like anything, you will get a feel for what you need/want. Good luck and we DO expect to see your creations in the gallery!!!;)
