Hello, fellow maker! This is a PDF file for a color reipe for the shades:
 
Pastel Orange
Pastel Green
Pastel Baby Pink
Pastel Lavender
These are the colors used in the pastel rainbow series. 
 
Each color requires only 4-5 shades of Sculpey Premo and Souffle clay. The PDF will also include tips and tricks to help you achieve smooth, bubble-free clay with this mix of colors. If you have any questions about them, drop me an email at helloannabullco@gmail.com
