Simple Stained Glass

I

f you want to assemble simple windows, first mark out the dimensions of their length and breadth on a wooden board, then draw scrollwork or anything else that pleases you and select the colors that are to be put in. Cut the glass and fit the pieces together with the grozing iron. Enclose them with lead cames putting in the nails and solder on both sides. Surround it with a wooden frame strengthened with nails and set it up in the place where you wish.
