Since I couldn't find cloud fabric anywhere in Hong Kong I came up with the idea to print my own. So the first step was to make a stamp. I used the back side of an old stamp and a foam craft sheet. I cut the cloud out of the foam sheet and glued it to the piece of wood. And the stamp was ready.
I used white fabric paint for the printing. The blanket was bought from a baby shop. And so I have a cloud blanket now!
