Just measured my leaders on my Tin Lizzie/Grace Frame. Serge around all edges of leaders after they are cut. Front leader is 9" (add about 1/2" to one edge and 3/4" to other edge for hems) 2nd one is 19 1/2" (add same amount for hems) and third is 26 1/2" (again add 1 1/4" for hems). My leaders are attached to metal poles with velcro...so the hem on that edge matches the width of the velcro. Other edge is serged and turned under about 1/2". My leaders are about 114" long (add 1/2" to each end for hems...so cut 115" long). By my calculations....buy 60" width fabric and then the length of the leaders.....mine would take about 3 1/4 yds. When adding the measurements for the leaders 9" + 1 14" (hems) + 19 1/2" + 1 1/4" (hems) + 26 1/2" + 1/1/4" (hems) = 58 3/4". So you are within the 60" width of your fabric and should only have to buy the length to match length of your poles/leaders. My fabric is kind of a twill/canvas. Not that heavy....but not lightweight like muslin. Mine has all kinds of printed measuring lines on it, but don't use them, so not needed. I will definitely make my own if I ever need new ones. By my calculations $80/3.25 = $24.61...surely you can find canvas for less and the sewing is not difficult. Hope this helps. Even if your canvas is not 60" wide, there is a little wiggle room in how wide you make your leaders....you could fudge probably an inch on each and still be good.
