That's a great idea, Hoppy. I see what you are saying, that sounds like a definite possibility.
Wasserpest - T! Thanks for the link. I was just looking at this just moments ago and came over here to see you linked it. I like the simplicity of the design and see that you used a speaker packaging?
Thanks, HX67! I hope to make you pleased of my attempts of copying some of your ideas.
I called around and there is a heating and air place that can order 30 PPI polyurethane foam that is 1" thick. I was wondering, could I buy two of these and 'sew' them snugly together with mono filament to make a 2" depth? Because if so, I can can get what I need for under $8. That would make things so much easier.
