My favorite class in design school was fabric design and I currently have a good stash of fabric dyes and paints. One project I worked on had me dyeing 150 shirts four different colors. That was a lot of fun and left my hands very interesting colors for days.
But I also know dyeing fabric is overwhelming the first time (and can be disastrous). I have some of my worse ones in a hidden box somewhere. I call it the box of shame. These tutorials would have been very handy back then.
See how cute they turn out!
