Glued edges and finished edges.

[JamesR]

I have been gluing and stitching edges for some time. I always assumed that the glue served two purposes. 

First, it keeps the pieces aligned while stitching.  

Second, it bonds the edges together so when they are burnished and waxed the seam stays closed up and looks like one piece. 

I am sure about the first purpose of glue but not so sure about the bonded edges for burnishing.

Can you still get good edges without glue?  What are your thoughts.  

 

Thanks
