I am trying to make the scallop trim to insert under the binding on a quilt like Ricky showed on the Grand Finale video offered Jan.-March of 2013. I thought I had taken good notes, but when I complete my edge stitch/blind hem stitch, it does not form a scallop, rather it just lays flat. What have I forgotten? 1" fabric strip folded in half (bias or straight of grain?) I used bias. Edge stitch/blind hem with zig going off the fold of the fabric, but no pretty scallop like Ricky. Video is off the website as far as I can tell. Help???
