A VERY useful lens shade can be made from a piece of old inner tube. First lay out a pattern on paper as shown in the drawing. Trace this pattern onto a piece of rubber from the old inner tube. Use a piece of blowout patch to fasten the ends together or provide a ¼ inch flap on one end and use rubber cement.
After the cement has dried, give the shade a coat of flat black paint inside and out.
This lens shade can be flattened and carried in the pocket, and will always come back to shape when wanted.—• Alfred Weber, Bridgeton, N.J.
