HEY. I did a tie-dye t-shirt (shown in previous post), and now I'm gonna show you how to do it! Yay for my first craft tutorial!
I used Dylon hand-dye for mine, so the instructions will vary - therefore I won't go into too much detail. But basically you'll need to dissolve some table salt in water, then add the dye and then put the tee in the water. Stir it around for like 15 minutes (sooo boring) and then every now and then for about 45 minutes. Rinse the tee straight after and then wash it (I'd recommend washing it separately for the first few washes, the colours might run). When it's dry, you're good to go!
The finished product is somewhere in this post.
Hope this was useful/fun/whatever,
