Easter lace eggs cookies

Many people ask me how I get the convex shape of Easter eggs cookies. 

Do I have the special equipment or baking dish? 

I wish I could have those baking dishes! 

But I use an ordinary spoon. 

I place on it already cut dough and put it on a baking sheet. 

Unfortunately, I did not have time to make a picture in time, 

but you can see from this photo, a spoon, which I used.
