  • 4 X 4 – A standard untreated 4X4 fence post. The normal 4 X 4 from hardware stores are actually 3-1/2 X 3-1/2 and they work well.
  • Sand Paper – I used 120-grit
  • White Paint – I used Behr Marquee Semi-Gloss in Ultra Pure White because it’s what I had on hand.
  • Red Paint – I used Behr Marquee Color Sample paint in Stiletto Love.
  • Blue Paint – I used Behr Marquee Color Sample paint in Elegant Navy.
  • Foam Roller
  • Mini Roller Paint Tray
  • Foam Brush
  • Painter’s Tape
  • Star Stickers – I used Contact Paper and my Silhouette to cut stars. If you don’t have a cutting machine, you could use my pattern below to cut your own out of contact paper or consider a Star Punch.
  • Homemade Wood Stain (optional)
  • Jute
  • 3/4″ Rope – One foot will do.
  • Felt – I used a red 9 x 12 felt sheet found in the craft section of Walmart.

How To Make DIY 4 X 4 Firecrackers

Old fence posts that were taken out and are laying on the ground.

I happened to have an excess of 4 X 4’s because we recently had our fence replaced but you can also use new 4 x 4’s from a hardware store. There are a lot of things you can make with 4 X 4’s, like a 4 X 4 snowman, so you can use the leftover wood for more projects!

Old fence posts cut and sanded into blocks for crafting.

Step 1: Cut your 4 X 4 into your desired lengths. I didn’t measure mine but these firecrackers are between 5 and 16 inches. Later, I made a taller set for our front porch.

Step 2: Sand your 4 X 4 firecracker blocks.

Step 3: After sanding, wipe the blocks down with a damp rag to remove any sand particles.

Step 4: Paint each Firecracker white.

Step 5: Once the white paint is dry, use painter’s tape to tape around your tallest Firecracker. I adhered painter’s tape around the whole thing to make sure my spacing was right. Then I removed the tape where I wanted to paint red stripes.

Step 6: Adhere stars to the medium-sized Firecracker. There’s no particular way this should be done. Put the stars on however you like!

Step 7: After you’ve applied tape for the stripes and sticker stars, repaint the blocks with white paint to make a seal over your stars and stripes. This will prevent the red and blue paint from bleeding through as much. Here’s a tutorial on how to paint perfect cut lines.

Step 8: Once the sealing coat is dry, paint red stripes and blue over the stars. I used a foam brush for the stripes and a foam roller for the blue. I felt the foam roller did a better job. I ended up doing two coats of red and one coat of blue.

Step 9: When your paint is dry, remove the tape and stars. It can be a bit tricky to remove the contact paper stars. I used tweezers to remove them.

Check out the Firecracker on the left in the picture above. Somehow I missed sealing with white paint on that one and the bleed-through was pretty bad. There is still bleed-through on the others but not nearly as bad. It’s probably impossible to completely avoid bleed-through, using old wood like this, but it’s nothing a little sanding won’t fix!

Step 10: Give all of your firecrackers a final sand for a rustic look. The final sand will help to disguise any imperfections or paint bleeds. In the picture below, check out the final sand on the block on the right compared to the block not sanded on the left.

Step 11: Wipe down the firecrackers with a damp cloth to remove any sand.

Step 12: To give the firecrackers a bit of a vintage look, I rubbed homemade wood stain on them. This step is optional!

Step 13: Cut red felt into 3-1/4″ squares (if your 4 X 4 is actually 3-1/2″ X 3-1/2″) and adhere to the bottom of Firecrackers with a glue gun. This step is beneficial if you will be using your firecrackers as tabletop decorations. If you plan to put them on your front porch, you can skip this step.

Step 14: Tie jute around your smallest Firecracker.

Step 15: Finally, cut a rope into desired lengths. I used about 5″ for the tallest Firecracker and approximately 4″ and 3″ for the smaller two firecrackers. I found new garden shears worked great to cut the rope!

Step 16: Adhere the rope to the top of each firecracker using your glue gun.

Frequently Asked Questions

Foam rollers seemed to work best for painting the 4X4s.

I used contact paper to make the stars but I think vinyl would work better.

I used the star pattern included in this post with my Silhouette cutting machine. You could also cut the stars by hand.

This step is super important to lessen the bleed-through of your final color.

If I were to make these 4 X 4 firecrackers again, I would drill a hole in the top of each one using a wood spade bit so the glue would be hidden and the rope would be recessed.

  1. I love this project and all was going well until I sanded at the end. I got a lot of blue in the white stars, which looked messy. Do you have any suggestions? I followed your instructions, except I used spray paint instead of craft paint and a foam brush/roller. The paint seemed dry, but maybe I didn’t wait long enough. I haven’t sanded the red and white 4×4 yet for fear of getting read in the white stripes. Any help would be appreciated! Thanks.

    1. Hi Rhonda! When I sanded my firecrackers, I sanded just in certain areas where there were paint bleeds and on the edges and corners. Enough to hide my imperfections and to make them look rustic. The paint colors did smudge some so I wiped them down with a wet rag and finished with a vinegar stain, which you can find here: https://sunshineandrainydays.com/make-wood-stain/. The paint definitely isn’t perfect but perfectly rustic!
