Galaxy Wood Slice Art Tutorial – Easy Painted Galaxy

Do you remember when I posted about shopping for craft supplies with The Shoppe at Somerset? One of the items I ordered was black gesso because I haven’t spotted it locally. Then, as life would have it, I didn’t actually use my black gesso for a couple of months! When I came across a large wood slice I purchased a while ago while cleaning up, I decided it was high time to put both items to work. After a bit of experimenting and planning, this galaxy wood slice art is what I came up with. I really hope you enjoy!

Galaxy wood slice art tutorialDon’t worry – when you’re painting a galaxy like this it really doesn’t matter if you “can’t draw” or “can’t paint.” If you can dab paint around with a sponge, you can make this galaxy wood slice art! Add a sawtooth hanger to display it on your wall, use a screw eye to create a cute ornament, or display your painted wood slice on a small easel!

What you need to paint a galaxy

  • Wood slice
  • Black gesso (technically optional but very helpful)
  • Craft paints in galaxy colors (blue, purple, pink, etc) as well as white & black
  • Flat paint brush. I used a 1/2″ brush
  • Painting sponge and/or foam dabber (if you have neither, use a foam paintbrush as a dabber)
  • Small paintbrush and/or old toothbrush (optional)
  • 1″ painters tape (optional)
  • Scissors, if you’re using tape
  • A palette, plastic plate, or, my personal favorite, a large plastic lid (from oatmeal, coffee, yogurt, etc.)
  • A sawtooth hanger, screw eye, etc. (optional – if you’d like to hang your wood slice)

How to paint a galaxy on a wood slice

Because my wood slice had a bark edge I wanted to preserve, I decided to create a zig-zag border around my wood slice using painters tape. You absolutely do not have to do this, but it’s easy and adds a nice touch! If you’d like to create an edge to preserve any bark and a bit of natural wood, cut your tape into 1/2″ strips and then cut each strip into a 1/2″ square. Position these squares around the wood slice’s edge to create a triangle/zig-zag border all the way around.

If you have black gesso, give the wood slice a good coat and allow it to dry fully. If you don’t have black gesso, you can use clear gesso and then apply a layer of black paint, or you can use 2-3 layers of black craft paint. Wood is porous, so the gesso prepares the surface for painting. Some of the paint will soak into the wood if you paint directly on it, which is why you will probably need multiple coats of craft paint to achieve the same level of coverage.

Once your gesso/paint is completely dry, mix up some paints for your galaxy! I put some turquoise, purple, and blue paint on a yogurt container lid and added bits of white and black to create a variety of shades. You’ll probably also want some plain white paint, so get a bit of it ready, too!

Grab your sponge or dabber and dab away! You may want to have either multiple sponges or a paper towel for cleaning yours handy. I started with a band of my lighter aqua up the middle:

Then I added darker aqua around the edges, followed by lighter purple, pure purple, and darker purple.

As you work, don’t be afraid to go back in and add more paint! I aded white paint down the center and some aqua on top of purple, for example. Just keep playing and blending until you’re satisfied!

Dab an old toothbrush or your paintbrush in white paint and use your thumb to flick paint at the wood slice to add dots for stars.

Once the paint is dry, you can also grab a small brush and hand paint in a few larger stars in white, gold, or silver.

When all the paint has fully dried, remove your painters tape. Add a hanger, if you’d like, and enjoy your awesome new galaxy wood slice art!

    Ooh, I saw this on your FB and thought it was really lovely! I like the same colors as you!! Though I don’t mind me some blush and grays..

    • Natashalh August 31, 2017, 12:24

      Grey and blush does have a nice, modern feel that somehow also seems classic. Maybe I should try crafting with the combo sometime!
