Stick with a wedged frame, fastening the canvas on slack and then
stretching it. Trying to stretch the canvas and _then_ attach it
whilst under load is a heathen notion.

Well MrD I make my own stretcher bars but they glued and screw,not the wedge
way and they have not loosened the canvas yet.

Isn't stretching both ways necessary?
