Babies!
No cute little smiles or messy diapers here.
Dina Kowal, from Split Coast Stampers has converted me to the use of baby oil as a blending agent with Prismacolor Pencils. Aside from the fact that I LOVE the smell, it blends so beautifully - it ends up looking so un-pencil-like. It almost looks as though you've used markers. I'm still experimenting with different techniques like a very light yellow or pink for additional highlights instead of white. I find that after applying several colors then blending with my stump and baby oil, that I can still go back and add more color highlights here and there.
So far, I still prefer using a kleenex as a final burnishing/buffing tool. I tried baby wipes but they took away a lot of color and the paper got too wet.
