A case lined with lens-cleaning cloth will help wipe away smudges whenever you stow your glasses.
Use pinking shears to cut out two 4-by-7-inch pieces of felt and two of lens cloth, available at pharmacies.
Sandwich the cloth between the felt, and sew them together on three sides. On one of the longer sides, leave 1 inch unsewn. Hemstitch the opening.
