Step 1: You Will Need
-A cup for that glass. (I don't know how to call it, but you can find it in diy/ jewellery shop or make it)
-Glue or hot glue gun
-Nail Polish (optional)
-Clay or polymer clay (optional)
Step 2: Glasses and Printed Picture
You don't have to print image. You can always draw the galaxy with Nail Polish. I didn't have all colours, but I'll try to explain it. Put dots with white colour for the stars. Put the same colour in one corner. Now take purple colour and glitter purple everywher on the left side. Then add blue colour to fill everything. Add black colour before blue Nail Polish is dried and mix it.
Step 3: Glue It
I have some ideas for that then. ---->
Step 4: Make It With Clay
Make nice circle with scissors or with scalpel. Colour it with Nail Polish after it dries. Now you can just glue the jump ring, but I made a ring.
Step 5: Glue Gun
Take the plastic part from medicine. Now make the plastic thin board and draw the pattern. Cut it of and stick the printed paper on it. Now glue the plastick part and decorate it with Nail Polish. Make a hole and add the jump ring.
