If you’re passionate about sustainability and are looking for ways to incorporate it into your daily routines, a sustainable desk coaster is an excellent starting point. This DIY guide will teach you how to create your own eco-friendly coaster for your desk. As a unique piece of functional art, your DIY sustainable coaster can be a reminder that small efforts towards environmental stewardship can have significant effects.

  1. MATERIALS NEEDED

For a DIY sustainable desk coaster, you’ll need to use sustainable and recyclable materials. Here’s a quick checklist:

  • Reclaimed Wood: This is a fantastic choice, not just for its sustainability but for its aesthetic as well. You can use salvaged pieces from old furniture or construction sites, for example.

  • Sandpaper: To smooth out the wood surfaces, particularly if your reclaimed wood is a bit rough around the edges.

  • Natural Oils or Wax: To serve as a finish, bringing out the beautiful grain in the wood and providing a level of water resistance.

  • Recycled Cork: This provides a softer base for the coaster to protect your desk.

  • Non-toxic adhesive: To adhere the cork layer to the wood.

  1. DIMENSIONS AND SHAPE OF THE COASTER

The ideal coaster size is often around 3.5 to 4 inches in diameter or width. However, sizing really depends on your personal preference and the kinds of mugs or cups you typically use. Standard coasters can be either circular or square, but you have complete creative freedom with this. Maybe you want your coaster to be hexagonal, minimalistic, or even abstract. It’s your coaster; make it your way.

  1. PREPARING THE WOOD

Depending on the condition of the reclaimed wood, you could have a few knots and rough patches. Your first step to creating a sustainable desk coaster is to smoothen these out. You can achieve this by using fine-grain sandpaper to gently sand the wood. Afterwards, clean it to remove any residual dust.

  1. MEASURING AND CUTTING

After prepping your wood, measure out the coaster size onto the wood using a ruler. Ideally, you should mark these areas with a pencil for accuracy. You can then cut through these measurements with a saw. If you don’t have a saw, consider going to a local hardware store for assistance.

  1. ADD DURABILITY AND LUSTER

To increase the wood’s longevity and aesthetic appeal, apply a layer of natural oils or wax to your coaster. Organic linseed oil or beeswax are excellent choices as they are non-toxic and sustainable. Rub the oil or wax into the wood generously and buff away any excess with a cloth, then leave it to dry.

  1. ADD CORK FOR EXTRA PROTECTION

The next step involves cutting a piece of recycled cork to match the coaster’s size and shape. Cork is one of the most sustainable materials you can find and also makes an excellent surface barrier for the coaster. It helps protect your desk from scratches and adds an extra dash of eco-friendliness to your project. Once the cork piece is ready, you can attach it to the bottom of the wood using a non-toxic adhesive.

  1. FINISHING TOUCHES

Now that the basic construction is complete, you might want to add some personal touches. You could stencil a design onto the wood, or if you want to go that extra mile for sustainability, consider burning a design into your coaster using pyrography techniques. Just ensure you’re in a well-ventilated area and don’t burn too deep, or you might weaken the coaster.

A DIY sustainable desk coaster is not only a great way to minimize waste but it also enables you to create something practical and beautiful. Through this process, you would be doing your bit to create a more sustainable world and be left with humble desk accessory to remind you of your eco-friendly efforts. A well-made coaster can also be an excellent handmade gift for eco-conscious friends or family.
