Mask, mix/blend pattern

[arthenics]

Hello,

I'm trying to create strass material and if glass is fine, if height is ok... I'm struggling with mask between the part that is glass and the part that support the strass (be it leather, plastic fabric or whatever). 

I have a graph for the glass with some output (IOR, color, translucency etc.).

I have a graph for the pattern of the strass (some sort of honeycomb pattern) with the pattern and its inverse.

Where I'm lost is for the masking/blending part.

While I'm at it, I'm using a value for translucency but then, blend node can't be used, should I replace the value and use a greyscale instead?
