You will find instructions on how to make the frosted glass panel here [http://www.home-dzine.co.za/crafts/craft-frosted-framed.htm], and the frame is built around the completed glass panel.
The nice thing about using tongue and groove for the picture frame is that it already has a pre-cut channel down one edge, which makes it easy to mount our piece of glass.
If you get confused when cutting the angles, cut one at a time so that you can fit the frame together as you cut each end.
You don’t need specialised tools to cut mitred edges for picture frames – a mitre box and backsaw do the job just as well.
A few light taps from a rubber mallet will help on areas that need a bit of coaxing, but only tap lightly to tease the glass into the grooved slot.
Apply a small bead of No More Nails adhesive to the mitred ends and attach corner braces with 12mm wood screws to hold frame sections together.
Leave the adhesive to cure overnight.
The strips are attached with a bead of No More Nails adhesive.
Although not heavy, for a frame this large it is always safer to have two hangers rather than one.
NOTE: Don't be a dumb blonde like me. it is easier and better to apply the stain and two coats of sealer before you assemble everything and then apply the final coat of sealer once assembled.
To add a bit of detail to the frame I stuck a strip of aluminium tape around the frame, as you can see in the main pic.
