Ideas for how to get so many jumpers...

I have been thinking of ways of how to collect the amount of jumpers that I need. 

I have started to notice more and more people wearing them... which is going to help. 

I am going to go out into the public with a camera and ask people if I can take pictures of them in their jumpers... I think this will look a lot more authentic as I don't want these obviously posed. 

I have decided against doing an actual photo shoot as I actually want these to be natural. 

I am also thinking of ways to hide people's faces. I want the focus to be on the jumpers, not the models. 

I am going to go to a few boutiques and charity/vintage shops with some friends and get them to try all the jumpers on. I am going to take a large amount of photos and then choose my 20 favourite from them.
I also have a few myself that I would like to use, and I know other people, including my housemates that I could use as well. 

I was also thinking of creating some flyers to put around the college asking people with jumpers similar to the ones that will be on the flyer to get in contact with me so that I can take a quick photograph of them wearing them.
