Sun Painting

Disclaimer
Many folks do not get the same results as I do with this project. There are also many folks who do. I’m not sure why there’s such a variation — I’ve tested it multiple times, and it has come out each time for me. I’ve considered taking this post down since I can’t figure out the issues or guarantee good results for readers. However, I decided to leave it up so that the readers it worked for still have access to the templates.
I love all the projects I share on this blog, but this project might be my favorite ever. From start to finish, this was a blast to do, and my 18 month old, my 3 year old, and a 8 and 10 year old that came to visit loved it. It really is a craft you can do with just about any age.
It’s also dirt cheap and uber simple. I used flour sack towels for the fabric. They come in a pack of 12 for about 9 bucks, and I cut one up for this project. We only used about half of it, leaving us with plenty of cotton fabric for future sun printing adventures.Â
The paint is literally just regular acrylic paint – this is the set we used. The secret to getting the sun print using regular paint is just to water it down. You can see the difference in the blue popsicle verses the others. The popsicle isn’t as sharp, and that’s because I was still getting the hang of how much water to add. What I discovered? More water = better!
And the last material you need is cardstock. This is another place where watering down the paint is important. If you leave the paint too thick, your cardstock may stick to it and ruin the fun.
The designs here use these printable templates: there are 2, one for the watermelon and flip-flop, and one for the popsicle and sun.
I absolutely love how fun these little summer images are!
Update
When wrote this post, I figured the difference in color came from the sun, hence the title. I now realize that the difference in color comes from the cardstock soaking up some of the paint from the fabric, which is why the exposed area is darker and the covered area is lighter.
Sun Painting, Step-by-Step
Materials
- 100% cotton fabric
- acrylic paint
- water
- bowl for mixing paint
- paint brush
- cardstock
- templates (watermelon and flip-flop, popsicle and sun)
- scissors
- foil
- cookie sheet
- the Sun!
Directions
Start by prepping your cotton. I used these towels cut into roughly 8×8 squares. We were making a summer bunting from the finished products, so we wanted a kind of undone look. I ended up leaving the ends cut and fraying.
Soak your cotton thoroughly with water, then wring it out. You want it damp, but not pooling water. Once it’s been wrung, spread it out on a foil-covered baking sheet.

Now you get to water down your paint. Add a small amount of paint (about 1 tsp) to your bowl. Then add about 2 Tbsp of water and mix it together well. You want your paint to be very thin – just slightly thicker than water. Add more water if you need to.
Pour the paint onto the fabric and use your paintbrush to make sure that the paint covers the entire thing.

I love how Alex has turned into a teenager now that he’s a whole 3 1/2 🙂 Don’t let the face fool you. He’s not thrilled about how many pictures I’m taking, not bored with his craft.
Once you (or your happy little helper) have covered the fabric with paint, take your cardstock template and press it down on the fabric. You want the entire thing to be pressed down firmly – especially the edges. That’s what gives you a crisp looking print.

Now, take your baking sheet and place it in the sun for 2-3 hours.
Peel the cardstock from the fabric, and check out your cool design!

Very interesting DIY tutorial.
Hi. Will this work on a small canvas?
I’ve never tried it. Canvas is less absorbent than the fabric, so I’m not sure. Sorry I can’t be more help!
Thanks I will try and see what happens.
I wonder if this would work on a tshirt?
Tshirts are usually part polyester and take dye or paint differently than cotton, but try and see. And washing may remove all evidence of your work
