Really cool "structures", thanks for the pics. Spruce sells 3/8 x .028(I think Paterek* recommends this wall thickness, anything thicker will tend to kink) for $5.25 a foot, the 3/8 x .035 for $2.94, 1" x .035 for $3.85, 1" x .028 for $7.25. The thinner wall is more expensive because? Where do you get your mtls and what do you use?

thanks, Brian
