I love sun catchers. Part of what I like about them is how different they look as the daylight shifts. They also have a completely different look hanging on a window versus a wall, which you can see here:
But what I like most about them is that they're easy to make and always pretty. Affiliate links below.
Easter Egg Sun Catcher
Cut two pieces of contact paper that are slightly larger than you want your finished sun catcher to be. Make a pattern for your egg, then use a Sharpie to trace the pattern onto the paper liner of one of the pieces of contact paper. Do not draw on the contact paper itself!
Cut narrow strips of tissue paper.
Place the piece of contact paper with the pattern drawn on it on your work surface. Peel the liner off the other piece of contact paper only, and place it sticky side up on the other piece. Now add strips of tissue paper and rows of sequins to the sticky surface. The tissue paper should extend beyond the edges of the pattern, while the sequins need to stay inside the lines.
Slide the lower piece of contact paper out from under the one you've been working on. Remove the paper liner and set it aside. Press that piece of contact paper on top of the first, sticky sides together, sandwiching the tissue paper and sequins inside.
Place paper liner with the pattern underneath the sun catcher, adjusting it so that it is lined up properly. Use paper clips to hold it in place if necessary, then cut along the line.
Poke a hole in the top of your sun catcher with the craft pick, then insert a length of embroidery floss. Tie a knot to make the hanger. Then hang it on a wall...
... or in a window!
If you do hang it in a window, be sure to check back at different times of day to see how the light changes.
