Easter chicks-18 for a £1 from Poundland
Like I said, there's not much DIY involved. Put the chicks in the vase, followed by the eggs. The effect, however, is really pretty and they have happily sat on my coffee table for a week now.
Edit: it's 5am and I have just swept the remains of this into the bin. Catsby knocked it off the coffee table so I had to get rid of the lot. You can't have anything nice in this house!
