Alfred,
I understand that you have a limited supply of material so it might be prudent to produce these last after you've filled all your orders. The inside pads, while nice to have, are also mostly unseen with carpeting covering them, so I'm not sure you would want to use up a limited supply of material like that. If you can get more material, or have someone make it for you, then by all means make everything you can.
Just my opinion and I'm sure there will be other ideas concerning this.
