fabric markers (I used 2 shades of a colour)
brushes (various sizes help)
This is how I did it: I went nuts with the markers, drawing all these spontaneous patterns - sorry, bad instructions, I know. But I did. Then I let the markers dry for a day before painting the linings of the hole. The fabric paint I used instructed me to wait at least 3 days for it to dry then I washed the shoes (using the machine, though it's not recommended). And finally, I dab some water colour on some parts of the shoes, creating soft hues all around. That's it. Visually, it goes like this:
I've got some confessions to make. First, the water colour thing was an accident. I did want to actually paint the whole thing with water colour but it went down the drain real quick. It was supposed to look like this pair from Valerie Chua but, it didn't. I tried to scrub it off but it didn't work so I decided to just make some hue-ish effect. Second, I first used a fabric marker for the darker colour and a paper marker for the lighter colour. Stupid mistake, really. After I put it into the machine, the lighter colour was washed right off and I had to start filling the gaps all over again. Since it was all hand-drawn, it was pretty obvious that I couldn't make the same pattern twice - I'm not a printer. If you look closely, you'll notice the differences between the right and the left shoe. So there you go. Hope you guys find it helpful and have fun DIY-ing!
