I love my Prismacolor pencils too! I have not used anything else to color with since I bought them back in September. I like the look of Copics but I cannot afford all the colors that I would want. So I bought the set of 120 pencils and I am super happy with my results.
I love coloring this way. I have even been teaching classes at my local scrapbook store about this technique. I have had two classes so far and one more to go for May. It has been a big success!
BTW, I use baby oil instead of gamsol (OMS). I found that I was getting headaches even though it is supposed to be odorless. Check out my tutorial
on my blog.
I use Archival Jet Black ink from Ranger on Georgia Pacific white card stock from Wal-Mart. I have never had any problems with bleeding or smudging either.
