Introduction: How to Make a Galaxy Print on a White Shirt

Most of the DIY's out there for this 'look' are started on a black shirt, and use bleach. But I had a white shirt that I really loved the shape of, and (of course) I spilled coffee on it. This is how I 'fixed' it.

Step 1: Gather Supplies

white T-Shirt
Fabric Paint
wax paper
old toothbrush
craft stick (or disposable wooden chopstick)
plastic bags or other dropcloth to protect your surface
cardboard & tape

Step 2: Build Shirt Insert

In order to prevent the paint from seeping from the front of the shirt, through to the back; you have to create a cardboard insert to go into your shirt. You can buy one, or make it from cereal boxes or other cardboard. Since my shirt was a weird shape, I needed to make my insert from scratch.
Cut the cardboard & tape pieces together to fit perfectly into your shirt. Take your time & get it right and it will make a big difference in the finished appearance of your shirt. (random paint spots seeped through to the back are not pretty)

Step 3: Choose Colors & Prep Paint

I like to use a small baking tray and a piece of wax paper as my painter's palette; super easy & fast clean up. 
Because you're painting with a sponge, you need less paint spread over a larger surface area. I achieved this by putting a small amount of paint on the wax paper & then folding the wax paper over & smooshing it. Wahlah; your very own mini rorschach!
Also, if this is your first time using this sponge (as it was for me) you may want to grab some scrap paper & just test it out & get a feel for the look you want.

Step 4: Block Out Your 'dead Space' Area

I'm no painter, but it's my understanding that you generally want to start with the darkest color on the bottom. & since you're starting with a white shirt, black is your darkest paint color & the one to start with. Use your sponge & black paint to plan out the areas that will not be covered by other colors. 
It's also easy to go back & add more to fill out space as you may discover you need to do.
You can see some of my inspiration images laying around. I've included the link below as a starter source for galaxy images.

Step 5: Paint!

Use your sponge & other paint colors to fill in the space not covered in the black. Work in sections & by paint colors.

Step 6: Make Stars

(I didn't get photos of this part, sorry)
Put white paint on your toothbrush & drag the craft stick across the top of the bristles. Drag the stick from the top of the brush Towards you- trust me- this will cause the paint to splatter away from you & create your 'Stars'. Use the toothbrush to splatter your stars across the shirt, as much or as little as you like.
And you're done!
