The wale(door to door salesmen) sell different things according to the seasons. When it starts to cool down and all during the winter there are wale that sell Khes(sounds like "case") and cambal. Cambals are just soft comforter types of blankets, thick and usually fuzzy. The khes is a thinner woven blanket(here is a very detailed article on khes and other woven fabrics common in Southeast Asia), that is very common in the Sindh and Punjab ares of Pakistan.
The khes wale usually come on bicycles, with the khes tied in a stack on the back and a couple on the front handle bars for display. Khes come in sets of two or four, and the plainer ones are usually still in one big piece that you have to cut and finish the edges yourself. There are fancier khes that have already been cut and have a finished edge, sometimes a fringe or tassels.
The less expensive, plain types of khes are generally only two to three colors and have a very basic checker type pattern. Other khes have elaborate floral motifs with five or more colors, and most are reversible.
The single khes is roughly four feet wide by six feet long, so the un-separated khes are about four feet wide by twenty four feet long.
