英文来的，好像说做网罩的！
(above) First lay out the frame on a properly cut piece of cloth.
(left) Then put a bead of glue all the way around the edge of the back of the frame.
(below) A 10 cent "acid brush" makes a good disposable tool for spreading out the glue and keeping track of how tacky it is.

ll corner #1 around the frame and set it into the glue. At this point, don't worry about getting the cloth to lay neatly on the frame edge:

The opposite corner, #2. As you can see, there will be a big diagonal crease in the cloth at this point:

Corner #3 - the right amount of tension will remove most of the crease from the previous step:

Pulling corner #4 into place removes the rest of the diagonal crease and sets up the cloth for the detail work. The remaining crease is due to the side of the cloth pulling towards the center under tension, since it is not stretched and glued on to the side of the frame yet:

Gently pull the long sides around the edge of the grill and tack them in place. This nicely eliminates that tension crease seen in the previous photograph:

Do the same with the shorter sides. At this point the cloth should be neat and taut, without ripples or folds as it comes around the frame. Work with it and adjust it as you go, if necessary:

In the next two pictures, I am cleaning up the corners:

Take advantage of the "stretch" in the cloth to get it to lay pretty much flat for 3/4 of an inch or so on the frame. Pull it up a bit off the frame then pull it smooth while pushing it back into the still-tacky glue. There is a bit of an art to this step - but so long as there are no nasty welts running right to the corner of the frame it will be ok.

Satisfied with the lay of the cloth, and having pressed it into the glue with the butt of a tool handle (not shown), next cut off the excess with a nice sharp knife:
