I have a Grace Machine Quilter frame (with the King extension) and want to make my own cloth leaders. The directions say I need a 14" for the back rail, a 10" for the middle rail, and a 3" for the front rail. The width of course would be the width of my frame.

Any advice on making my own? I will be making these tomorrow and thought I'd ask here in case anyone has made their own. I don't want to buy ready made ones - saw them for about $80. and up, just for the 3 of them.

Thanks.
