I am building a GWS A-10, but I discovered that they didn´t include the CA hinges. After searching through my shop I found a roll of Velcro Treeties about 3/8" wide of the type used in gardening. I first tried beding it several times to be sure of its strenght. as it was tough enough I just cut it in lengths as needed and voilá, perfect CA hinges.
They have rough surface that helps the glue sticking to it. And the dimensions are perfect. Also very cheap.
