I was in the front of a big-city supermarket today when I saw a display of hand-made "gift sacks." They were made out of two rectangles of cotton cloth sewn together, with a 1-inch hem at the top through which a brightly colored ribbon had been threaded. They were selling for $3 to $4 a piece, a price very competitive with the cheap paper gift sacks that were sitting next to them. I imagine that someone even minimally proficient with a sewing machine could bang out ten of these in a couple of hours. Profit margin would be nearly 100 percent for somebody with spare fabric lying around. Not a huge money-maker, but probably a decent idea for a part-time income.
