Tying refers to using thread or yarn tied in knots to hold the quilt sandwich together rather than quilting with needle and thread.
An arrangement whereby the seller of some product or service requires, as a condition to the sale of that product (the tying product), that the buyer purchase some additional product (the tied product). The tying arrangement is unlawful when the seller has some power over the market for the tying product. Tying arrangements are generally per se illegal, assuming that the selling firm as the market power to force the arrangement upon its customers.
After the wool is shorn it is rolled into a neat bundle and tied with a paper fleece tie.
Tying is the practice of making the sale of one good (the tying good) to the de facto or de jure customer conditional on the purchase of a second distinctive good (the tied good). A classic example of de facto tying is the selling of razors at a loss and making the profit on the blades. Cell phones and printers sold at below cost, the profit to be made on the subsequent minutes or printer cartridges, are also common.
