Instructions:

Collect several glass bottles of different colors. Clean them thoroughly and remove all labels.
Using a glass knife, carefully cut the bottles into flat pieces. Wear protective gloves and safety glasses for safety.
Arrange the glass pieces on a flat surface to design the stained glass pattern. Experiment with different layouts until you find a pattern you like.
Use a glass sander or sandpaper to smooth the edges of the glass pieces.
Align the glass pieces to the window frame, using lead or copper tape to hold them in place.
Apply flux to the joints and use a soldering iron to solder the components together, ensuring a strong connection.
Once the soldering is complete, clean the glass thoroughly to remove any residue.
Secure the stained glass panel to the window frame using glass glue or epoxy.
Allow the adhesive to dry completely before installing the window in the desired location.
