Easy way to blocking crochet squares

I'm sure I'm not the first one who found it out. Well ... one day I will do momentous discovery. 

What do you need? 

1. Your wavey crochet square

2. Pillow

3. Pins

Simply pin your crochet squares to the pillow. Give the shape/size which you need. Hold in pins for one hour (more and less). I did not use iron or water.

Have fun !
