Actually that isn’t the issue I really have. I wanted from the beginning to target specific peoplw with the pencase and for the most part, I have exactly the contingent I wanted.

After the initial questionaire went out the one thing I was most concerned about seemed to be unfounded. I was actually worried about whether the testers wore belts!
I had made the pencase with a fixed belt clip which I actually use on my pocket in the field. I wear jeans usually so they are tough enough to handle the clip.
But I realize the belt clip might be a little narrow for heavy leather belts. I honestly feel the case works without the clip which might be a subtle change derived from the analysis of the data.
Since many answered that they don’t often draw or work in the field, they might be open to a version without the belt clip.
Interesting way to read the data.
