I like the mini SWAKOP idea, that seems more manageable than tackling the whole thing in one go. I'm pretty hopeless at entering most competitions - still working on my home-furnishing ones from back in January...
Did someone already mention fabric embellishment, like printing or stamping, embroidery, etc on your fabric then make your garment? That could be good.
I'm a bit scared to make any suggestions, 'cos I feel I'd have to enter if you run a competition that I've suggested and that's a whole lot of pressure to lift my game...
