|I've used a Sweet Stamps stamp.|
I've used Prismacolor Pencils on black cardstock.
I had to test out the colors on a bit of scrap paper
before first. It is easy to tell what colors will show
up and which will be bolder or softer in color.
Start with the lighter colors then work your way
up in color intensity. Little tiny details are hard
to create so working slowly will be a great benefit.
