I know, I know… Baby Shark mania here.
So I wanted to make some fun caution signs to put outside of our house for the guests coming into our little man’s baby shark party because how fun is that? I decided to make these fun signs and it really did not take that long. Longest part was waiting for the paint to dry! (Sorry about the madness going on in that photo… Nemo didn’t want to help me clean up the creative mess! And toys… so many toys.
All I did for caution sign inspiration was do an image search of “shark caution signs” but you could also use this for anything caution sign related… construction being a big one that comes to mind. I printed out my design to have it as a reference. One of the signs I picked out was one with a big shark and although I am decent at free-handing things at times, a shark may not be one of them. I did a second image search of “shark shadow clip art” and found one I liked, printed it and then I copied it at 150% magnification. If you don’t have this option, you could attempt to copy and paste the image in a Word/ Pages document and enlarge it.
I’ve learned something in this process… cheap foam poster board curls when painted, haha. I will have to flip these over and weigh them down with something to help encourage them to flatten but I am not too concerned. You could always use cardboard, which I had originally planned to do but there were not any big empty boxes at work and I needed to get them finished.
Here is what I used!
I went to my favorite place.. the dollar store. I purchased two pieces of foam poster board, one jar of yellow tempera paint, one thick black sharpie marker… AND THAT’S IT. I spent $4 total on these two signs. I plan to use some metal stakes we have to attach them to when putting them outside but the Dollar Tree also sells reflective stakes you use to mark around your driveway for plowing, in our snowy region of the world, there are garage sale signs you could attach it to or look around and get creative! There are a bunch of things you could use. I used a paint brush I had on hand, but they sell brushes there as well if you need one. You could also spray paint if you have it. If you’re using cardboard, you may need to put a few coats on it to cover up designs that were on the box.

Next, I measured out a square and cut! You could be precise and use a ruler or yard stick. Here’s what I did:

Since the foam board is rectangle, the short end of one can be used to measure a square on the other. Lay one down horizontal and the second on top vertical. Line up the edges and draw your cutting line.

Cut the foam board with a utility knife, exacto knife or open the scissors and score it. I don’t recommend using the scissors to cut it normally because it can leave jagged edges or swerve unintentionally. Once you score the foam board on one side, flip it over and bend it along your line. It’ll give you a second line to score on.
The next step is to paint it. I used my yellow tempera paint and painted a light coat. Let it dry completely before moving on.

Once it is dry, begin creating! I used a thick permanent marker but you could also use black paint with a small brush. I started with the outside line around the sign. I know my lines aren’t perfect, I figured it’ll be outside and people won’t be staring at it, haha.

Next, I took my enlarged shark, cut the edges of the paper to give me space to see where I am placing it, and then this is the best part.. you don’t need fancy equipment to do this. Just a pencil or pen. Foam board is very pliable and if you trace something with just a little force, it leaves an indentation on your board, giving you the template to fill in with paint or marker. Place the image you want to put on your board down and gently trace the image. It might be hard to see on my next photo but there is an indentation of the shark that I had traced. I also just free- handed the wave part above the shark image.

Then I filled in the shark with my marker and drew the waves above. I have horrible handwriting so for the words on this sign I typed them on my computer, enlarged them, printed them and then used the same technique as the shark where I traced the letters then filled them in. If you’re blessed with great handwriting, you could always just free hand it!


Then ta-da! That one is complete!
The second one I chose to do was easier. Same step of drawing in the outline on the edge. Then I honestly just looked at my printed picture and free- handed it because it was a simple design. I drew it lightly with pencil first, then filled it in with the marker.

I also decided to round the edges of the foam board a little bit to make it look more similar to the real signs. But that’s it! Super cheap, super quick and SUPER fun! A great way to add a little bit more crazy to your party 😉
