I am trying to find a binding tool for my good friend Eileen. She saw a special binding tool demonstrated at the International Quilt Festival last year that folded out rather long. She has regreted not buying it all year and returned to the Quilt Festival this year to find they were not there. We can't find it anywhere on the internet. Does anyone know what this is called, have they seen it or know where to buy it? Any help would be greatly appreciated!
