Prepare your pattern and be sure that you have it the way you like. Carefully cut out all of the pieces from the pattern and reassemble to make sure it still fits together the way you like it.
Trace your pattern. You will need to trace the various pieces on the various colors of glass you will be using. Trace near the edges to save glass. If possible, place pieces with the same colors near each other for ease of cutting and to save glass.
Cut your textured glass. Usually you want to cut on the smooth side. To use a glass cutter, you must begin at one edge and make one continuous score in the glass to another edge. There can be no skips in your score or the break will not happen the way you like. Make sure to check that your line reaches the edge on both sides beginning and end. Use your glass pliers to gently grasp the cut piece. It should be easily removed from the larger piece. If not, set the glass down on your working surface and tap gently with the pliers along the cut to help to release it.
Assemble your cut pieces. Be sure they fit together the way that you like and cut and/or grind any pieces that do not fit together properly. Apply your copper tape. Center the tape on the edge of each piece and run it all the way along, flattening the excess edges to the front and the back of the glass. This will create a metal line on the edge front and on the back so the solder can stick.
Arrange all of your coppered pieces or textured glass and flip them over to the back. Begin on the back so that you can get the hang of it. Apply flux liberally with a paint brush to all the copper. Prepare it for soldering and plug in the iron.
Apply the solder to the hot iron. Observe how it liquefies and becomes drops. Apply the liquid to the copper in smooth strokes. Cover all of the copper in solder. It will take time to learn to make smooth, uniform lines between the glass. What's important is that all the copper and empty space be filled and covered.
Solder around the edges, being careful not to damage your working surface. You can even lift your piece up if necessary since the solder on the back has secured all of the pieces in place. Flip your creation over. Solder the front then you're done.
