Here are two experiments I’ve tried to make an icy blend. I used these for the snowflake cane in the January 2015 issue of Cane Builder.
First I just used Premo brand ultramarine and white. This made the lower set of blocks that I’m holding.
I wanted the blend to be a little brighter, so the next time I inserted a curved section of turquoise. This makes the top set of blocks.
