Cut the design with my settings. With this size, the holes are fine for a 6-sting embroidery thread to pull over even twice or 3 times, if you want to play with different colors.

You can decide on the main color of the earrings; I am using a simple wooden lasur to add a main color, and give a nice tone for the wood. 

You can use any kind of paint, lasur, or coat; just make sure that the holes remain clean, and the most important part to wait until it is completely dried.

Choose your favorite color(s), and thread the needle. Pull the thread thru on one hole, but leave a little part out. Put a small dot of glue at the back, close to the hole, and move the end of the thread there. Push it a bit, keep your finger there to make sure that it won't get free. When it is secured, you can start the embroidery part - move from one side to another, and simply run thru on all holes. 

Once you reach the end, cut the end of the thread, and add a small glue at the back close to the hole (as on the other side), and put the thread end there. Wait until it's secured.

You'll need 2-2 rings and 1-1 earring hoops, and add them to your earrings. Then - you are ready to use!

Make them in different color combinations, so you will have a full set.
