This is easy and fun to do, so guys before you go and buy tie dye or dip dye stuff, please have a look in your closet for any old clothes you can use to make your own. There are really useful tutorials online here and here. Before you start, make sure you wash the fabric beforehand. I prefer to dye when its damp as the colour blends better, but that is up to you. If you want a more dramatic effect dye the article of clothing when it's dry. Also, always make sure you use gloves to protect your hands from the dye. I find clipping the top of your clothes to a hanger or a stick will help you control the dip and you can peg it on to the sides of the container while soaking the dye.

Ombre the top purple and bleach the bottom
Fushia and Lavender Denim Jacket
This one was a little more time consuming as I had to dye, re-dye and bleach the jacket a few times to get the right shade...but I'm pleased with the result.
