High quality stained glass is used in the making of this decorative heart design. The colors can never fade. The sun catcher is finished with decorative solder work that is very seldom seen on most stained glass pieces on the market. An attractive chain is attached to each piece. Due to the size of our suncatchers, they should not be hung with suction cups. We suggest that you attach a length of clear fishing line from the chain to the top of your window and secure the fishing line with a nail or screw. This will keep the heart and flower sun catcher secure.
