When I need a low cost option for a backing.. I premium Kona muslin at Jo 'anns. When I am at a loss for what to use my 50 percent off coupon , I pick up 3 yards . With the coupon it works aout to be about $7.00 yard for 108 wide. The premium muslin is quite nice, but there are some lower cost options as well. They do have some printed wide backings for about the same price , but the quality is not the same as the premium muslin.
