Hang the stained glass suncatcher in a window, where daylight comes through the glass; that is what lights it. The acrylic and glitter resin panels arrive ready to hang and catch the light from the front, so a wall facing a window or a lamp suits them. The ornament hangs on the tree.

Which window for the suncatcher?
Any window with daylight. In the US a south- or west-facing window lights it longest, and a west window puts the evening sun through it; a north window gives a softer, even light that keeps the colors calm. After dark, a lamp in the room turns it back into a picture of the place.
How do the panels hang?
The acrylic panel arrives ready to hang, its clear float frame held off the wall by corner standoffs, so it throws a soft shadow. The glitter resin panel arrives polished and ready to hang too. Use a fixing that suits your wall, and hang either one where it will not be knocked by a door or a passing shoulder.
Is direct sun a problem?
Not for the glass. For the resin it can be: any clear resin yellows slowly in hours of strong direct sun, so give the resin panel a wall the sun only passes over. The acrylic is happiest out of the hottest midday sun as well.
And the ornament after the holidays?
Wrap it in tissue and keep it somewhere it cannot be knocked or crushed. It is glass, so it wants a box of its own rather than the bottom of the decorations crate. Cleaning is in the care guide.
