Things You'll Need
Window suction cup
A suncatcher is a decoration typically made of stained or clear glass, which reflects natural outdoor lighting. Suncatchers can add a hint of color and aesthetic interest to any room in your home that has access to natural lighting from a window. To display your suncatcher for optimal effect, you will need to hang it in a window. In most cases, you can hang your suncatcher in a window in less than 10 minutes.
Measure an 8-inch to 12-inch section of thread with a ruler, depending on how far you want your suncatcher to hang down. Cut the thread to length with scissors.
Feed one end of the thread through the hole in the hanging extension of a window suction cup. Pull the thread through until there is an equal length of thread on each side of the hole.
Feed one end of the thread through the hanging ring on the top of your suncatcher. Tie the ends of the thread in a knot.
Position the suction cup on the window so that the suncatcher hangs near the center. Press the suction cup gently against the glass of the window.
Choose a window that faces east if you want your suncatcher to reflect the greatest amount of light in the morning or a window that faces west if you prefer maximum reflected light in the evening.
Use string or wire instead of thread if you plan to hang a large or heavy suncatcher -- thread may not support the weight of larger suncatchers.
