Turning a used sail into a durable tarp: A step-by-step guide

Repurposing old materials is not only sustainable but also satisfying, especially when you can transform something worn out into a functional tool. One of the best examples of this is converting a used sail into a durable tarp. Sails, designed to withstand harsh weather and tough conditions, make for excellent tarps when their seafaring days are over. In this guide, we’ll walk you through the process of turning a used sail into a sturdy tarp that can serve you for years to come.

Why use a sail?

Before diving into the steps, it’s worth understanding why sails make great tarps:

  1. Durability: Sails are made from strong, weather-resistant materials such as Dacron, canvas, or polyester, designed to endure wind, salt, and UV rays.
  2. Water resistance: Most sails are treated to be water-resistant or waterproof, making them perfect for use as tarps.
  3. Sustainability: By repurposing an old sail, you reduce waste and give new life to a material that would otherwise be discarded.

Materials you’ll need

  • Used sail: Ideally made of Dacron, canvas, or polyester.
  • Sharp scissors or a rotary cutter: For cutting the sail fabric.
  • Sewing machine (optional): For reinforcing edges and stitching hems.
  • Heavy-duty thread: UV-resistant polyester thread works best.
  • Grommets: Metal or plastic grommets for tying down the tarp.
  • Grommet tool kit: To secure the grommets in place.
  • Measuring tape: For precise measurements.
  • Marker or chalk: For marking cuts and folds.
  • Binding tape or webbing (optional): For reinforcing the edges.

Step 1: Inspect and clean the sail

Start by thoroughly inspecting the used sail for any tears, holes, or weak spots. Clean the sail with mild soap and water to remove salt, dirt, and mildew. Allow it to dry completely before you begin the transformation process.

Step 2: Plan your tarp size

Decide on the dimensions of your tarp based on your needs. If you’re making a tarp for camping, a common size is 8×10 feet, but you can customize it according to your requirements. Measure and mark the sail fabric with a marker or chalk.

Step 3: Cut the sail

Using sharp scissors or a rotary cutter, carefully cut along the marked lines. If the sail has reinforced edges (called the leech, luff, and foot), consider incorporating these into your tarp for added strength.

Step 4: Hem the edges

To prevent the edges from fraying, fold them over about an inch and sew a hem. If you have a sewing machine, use it to create a strong, straight stitch along the edges. If you don’t have a sewing machine, you can hand-sew the hem, but ensure your stitches are tight and even. For extra durability, you can sew on binding tape or webbing along the edges.

Step 5: Reinforce corners

The corners of the tarp will endure the most stress, so it’s crucial to reinforce them. You can do this by folding the corners over twice and sewing them down securely. Adding a triangular patch of fabric from the leftover sail material can also help reinforce the corners.

Step 6: Install grommets

Grommets are essential for tying down your tarp. Mark the positions for grommets along the edges and at each corner, typically spacing them 12-18 inches apart. Use a grommet tool kit to install them securely. Ensure the grommets are placed through both layers of fabric if you’ve folded the edges.

Step 7: Test tour tarp

Once your tarp is complete, test its durability by setting it up outdoors. Check that the grommets hold firm under tension and that the tarp can withstand various weather conditions.

Step 8: Maintain your tarp

To ensure your new tarp lasts as long as possible, store it in a dry place when not in use. Clean it occasionally, especially after exposure to dirt or saltwater, and check for any wear and tear that may need repairing.

Conclusion

Turning a used sail into a tarp is a practical and eco-friendly way to repurpose materials that have served their original purpose. With a bit of effort, you can create a versatile, durable tarp that will provide protection and cover for many years to come. Whether you’re camping, covering equipment, or just need an extra layer of protection, your homemade sail tarp is sure to stand up to the elements. Happy crafting!
