Here is my fence before:
You start with a bunch of plastic Easter eggs (I got mine last year after Easter when everything goes on sale. I paid only 50 cents for a huge bag! Its smart to buy at that time because plastic eggs wont go bad). Make sure that they are the kind that have holes on the top and that they have a small piece of plastic between the egg to connect the top and bottom half. Why? You will need the holes to pull the ribbon through and you want the egg top half and bottom to be connected so that every time it rains or its windy you wont be loosing pieces of the egg and it will always be intact.
Pick a pattern and decide what colors you are hanging. The bag I opened had only these colors and I decided to just do one of each and start over as my pattern. I start by putting the string through the egg and tied it on. Decide how long you want them to hang and how far apart. I placed mine 3 fence links apart and made the ribbons length in a pattern as well.
Slowly but surely you will see progress and it will be super cute! For the fence door I used one long ribbon and put on eggs in a different pattern and hanged it from one end to the other.
We did a couple more touches like giant plastic Easter eggs in the grass and I will probably keep adding until Easter so that when the kids come over they are sure to have a fun time! Here are pictures of the finished fence:
