Now that you've glued along two connecting edges, pull your fur tight (or at least not loose) and glue it along the next edge and then the final edge. On this fourth and final edge you may have some problems with too much or too little fur. In my case I had a teeny bit too much slack. I distributed the slack evenly over a 6 inch length and this eliminated the problem. It's probably best to glue the hinged side last because this side is the most hidden.
