Recently I needed to separate out some paperwork into two areas. Both area's needed two folders each for them. My vision was to have Blue ones for one area and Green for the other (actually, the colours wouldn't really matter but the colours went with the logos making it easier to remember which was which!) I was volunteering at the LifeLine Book Fest and thought I would grab some cheap folders (at 50c each I was unlikely to ever get a bargain like that again!) and I managed to get two green folders but only one blue one... I found a purple one and in the interests of having everything match (and not spending a penny more than I had too) I bought the purple one and bought it home with the intention of changing its colour to blue... Here's what I did... This folder is one of those ones that feels like its made out of canvas but I suspect hats its a woven plastic of some sort really. : Changing the colour was as easy as simply painting it with water based acrylic
