Gather Materials

Getting your hands on the right tools and materials is your first step to success. Think of it as preparing a delicious recipe – you need to have all the ingredients in place before you start cooking.

Similarly, for this DIY project, you’ll need the following items: plywood (the canvas for your masterpiece), a jigsaw (the paintbrush of woodworking), a drill bit (to make an initial hole for the jigsaw), a tape measure and pencil (for marking out your square accurately), and sandpaper (to smooth out the rough edges and give your work a polished look).

Make sure to pick tools that you are comfortable using. Remember, this process is not just about the end product, but it’s also about enjoying the journey of creation. Let’s gather these essentials and brace ourselves for the exciting task ahead.

Mark the Outline of the Square on the Plywood Using a Pencil

Now that you’ve gathered your tools, it’s time for the real fun to start! Let’s begin by marking out the exact shape and position of the square hole on your plywood piece. Grab your tape measure and pencil, and get ready to make your mark.


As you go about this, I want you to imagine yourself as an artist sketching the first outlines of a new masterpiece.

It’s not just about technicalities. It’s a creative process that needs your attention to detail and a steady hand. When you measure and mark the area to be cut out, remember, precision at this stage will determine the professionalism of your final product.

Measure the dimensions of the square hole you want, and mark the four corners on the plywood with your pencil.

Use the edge of the tape measure or a ruler to draw straight lines connecting the corners. There you have it – the blueprint of your square hole, ready to be brought to life. This is your artwork in its nascent stage, waiting for the next step to shape it into reality.

Drill Pilot Holes at Each Corner of the Square to Make it Easier to Cut with a Jigsaw

Imagine you’re about to embark on a thrilling expedition, and you need a starting point. That’s exactly what we’re going to do next. Your square outline is your roadmap, and the pilot holes are going to be your starting points.

Get hold of your drill and carefully place the bit at one of the corners of the square you’ve marked out.

Take a deep breath, and with a steady hand, drill a hole. This is your first step into the exciting world of woodworking! Feel the power of the drill as it smoothly penetrates the plywood. Now, repeat this process for the remaining three corners.

These pilot holes are more than just holes; they’re your gateways into the journey of cutting out your square hole. They make the daunting task of following the pencil lines with your jigsaw a breeze.

So, take your time, relish the moment, and make sure you’re drilling these holes at a comfortable and controlled pace.

This isn’t a race, after all. It’s an art, and you are the artist. Once you’ve drilled the pilot holes, you are one step closer to your masterpiece. Step back, admire your work so far, and prepare yourself for the next stage of this creative journey.

Cut Along the Lines Made by the Pencil with a Jigsaw

You’ve laid the foundation, you’ve sketched the blueprint, and you’ve drilled your starting points – now comes an exhilarating part of your woodworking journey, cutting along those pencil-drawn lines to create your square hole. As you reach out for your jigsaw, feel the anticipation of bracing a tool that’s about to bring your vision to life.

Remember, you are not merely a carpenter at this stage; you are a sculptor, and the jigsaw is your chisel. Be mindful of the power that you hold in your hands. As you position the blade of your jigsaw into one of the pilot holes, take a pause.

Feel the moment. Then, with a careful and steady hand, guide the jigsaw along the pencil lines, connecting the dots from one corner to the next. The hum of the jigsaw and the falling scraps of plywood are a testament to your creation coming to life.

As you navigate your jigsaw, remember, it’s not about speed, it’s about control. Let the tool do the work while you guide its path with accuracy and precision.


Don’t let the noise or the power of the tool intimidate you. This is your concert, and you are the maestro, directing how this symphony of creation unfolds.

Once you’ve cut around your marked square, step back and admire your work. There it is, the square hole that was once just a vision in your mind, now a tangible reality in your plywood.

It’s a testament to your patience, your skill, and your creative spirit. Let’s move on to the final steps of refining and polishing your masterpiece.

Smooth out any rough edges using sandpaper

As you stand there, inspecting your handiwork with a sense of accomplishment, you might notice some rough edges to your square. Don’t worry, this is where your sandpaper comes in. Think of yourself now as a jeweler, delicately polishing a precious gem.

Grab a piece of sandpaper, and feel its gritty texture against your fingers. This simple, unassuming tool is about to transform your work from a raw product into a smooth art piece. Start by gently rubbing the sandpaper along the edges of the square.

Feel the friction under your fingertips, and listen to the rhythmic scratch as you smooth out the roughness. This is a tactile experience. It’s not just about creating something but about connecting with your work through touch.

Take your time. There’s no rush. Feel the square edges soften and smooth under your careful ministrations. As you’re sanding, you’re not just refining your project, but also cementing a memory of this creative journey that you’ve embarked upon. So, savor this moment.

Appreciate the transformation unfolding under your fingers. Once you are done, step back and take in the sight of your well-crafted, smooth square hole. And there you have it – you’ve successfully completed your woodworking project.

Your hands, your tools, and your creativity have transformed a simple piece of plywood into a testament to your craftsmanship. Congratulations on your achievement!

Vacuum Up Any Sawdust Left Behind and You’re Done!

You’re standing amid the remnants of your hard work, the sawdust. It’s like confetti celebrating your achievement, but it’s time to clear the stage. Channel your inner clean-up crew, grab your vacuum cleaner, and let’s finish this in style.

Feel the hum of the vacuum cleaner as it springs to life in your hands, ready to erase the traces of your creative process. As you guide the nozzle over the surface, watch as the sawdust disappears, revealing the pristine state of your workspace and your beautifully crafted square hole.

This might seem like an ordinary task, but it’s a part of your journey. It’s the final bow after the performance, the finishing touch on your masterpiece. So, let’s do it with the same enthusiasm and pride with which you’ve carried out every step.

Now, stand back and admire the clean, sawdust-free area and your accomplished task. You’ve transformed a simple plywood piece into a testament to your skill and imagination.

Soak in this feeling of success – you’ve earned it. Well done, you! You’ve not just built something with your hands, you’ve created a memory, a story worth sharing.
