On the back of the panel film is a raster / grid, which makes it a very simple, symmetrical / straight / rectangular vorzumalen forms / figures and cut accordingly.
The desired shape can then be easily and with a little care and completely bubble-free and holds tight, super.
Only the outermost tines attached our star can for something, but everything else keeps bombproof, but can always remove without residue, simply peel.
We are really totally satisfied and I am always very proud when our little one again imagines the whole penguin and "Gagag" makes ... :)
So maybe not only cut out a rectangle, but quiet times be creative and miterfreuen on the enthusiasm of the children!
