I was so excited when I saw this idea at This is My Life.
This took me under an hour and that was with little helpers and interuptions. Minus that and you could do this in 15 mins!
I only bought 2 packets of plastic eggs (around the 6cm sized ones) and it wasn't enough. I have plenty of old eggs from easter last year, so used a few of the smaller ones from there. So to be safe buy yourself 3 -4 sleeves of eggs - I suppose it depends how big you make the circle.
Basically glue gun on the plastic eggs to a cardboard wreath in a circular motion with pointy ends facing outwards.( I made my wreath out a cereal box - two layers to make it sturdy)
Add a bow and string and attach to your door.
so happy looking!
