So, i work in a studio, we do alot of artworking, we're all creative types.
The actual studio is pretty nice, we have our own fridge, we all have decent computers, but recently we had the end wall put in place. Which for a few months has been rather bare.
I found this 'window cut outs' of some printed folder we had been doing, and thus, the Cut Here Door was invented.
I used a simple plumb line to get it all straight (a pair of hefty paper scissors, and some string)
I measured one of our doors for size, then went about sticking the small bits of card to the wall using double sided tape.
I then cut out a large pair of scissors from one of the folders to match.
