No, Phil. The answer is regretfully no. I agree about the cost and I 
never tried his paper thinking that my pain level starts at 50 cents. 
There are lots of companies that make money on 'specialty papers',

high. Just an example. It would be great to buy a yard of paper and 
sell it as inch-sized bits. Mike
