Easter is coming soon and I hope that alot of you will find this instructable helpful. I'm going to show you how to make giant Easter eggs out of regular insulation polystyrene. I used 100 milimeters thickness polystyrene for making 1 meter eggs. You can use this tehnique for making almost any round shaped object.
Step 1: Draw the Egg
First of all you should know how to correctly draw an egg. I'm usually using circles to draw the eggs, just like in the picture. At this point you also need to choose the polystyrene thickness and use it on your scale drawing. This way you'll be able to find the diameters of the circles you'll be cutting later out of insulation polystyrene. Don't worry, you'll see in a minute exactly what I'm talking about.
