Materials You'll Need

Gather these supplies before you start:

  • Fabric for the top layer (cotton, polyester, or fleece)
  • Waterproof material for the bottom layer (vinyl, PVC, or waterproof nylon)
  • Batting or insulation (optional, for extra comfort)
  • Polyester thread (for durability)
  • Sharp fabric scissors
  • Sewing machine (or needle for hand sewing)
  • Pins or fabric clips
  • Measuring tape or ruler
  • Iron and ironing board
  • Fabric marker or chalk
  • Optional: Decorative trim or edging for a polished look

Step-by-Step Guide to Making Your Waterproof Picnic Blanket

Step 1: Choose Your Fabrics

Selecting the right fabrics is crucial for comfort and functionality:

Top layer options:

  • Cotton: Breathable and soft, ideal for warm weather picnics. It's natural and feels great against the skin.
  • Polyester: Durable and quick-drying, perfect for frequent use. It resists wrinkles and maintains its shape well.
  • Fleece: Warm and cozy, excellent for cooler outdoor gatherings. It's lightweight yet provides excellent insulation.

Waterproof bottom layer options:

  • Vinyl: Highly waterproof and easy to clean but less breathable. It's very affordable and comes in various colors.
  • PVC: Durable and waterproof, but consider eco-friendly alternatives. It's tough and can withstand rough surfaces.
  • Waterproof nylon: Lightweight and flexible, though potentially less durable. It's great for a blanket that needs to be packed away frequently.

Step 2: Measure and Cut Your Fabrics

Choose a size that suits your needs:

  • Small (for 1-2 people): 45" x 60"
  • Medium (for 2-4 people): 52" x 68"
  • Large (for 4-6 people): 60" x 80"

Cut top and bottom fabrics to your chosen size, adding an extra inch for seam allowance. This extra fabric ensures your blanket will be the desired size after sewing. For added precision, use a rotary cutter and cutting mat if available.

Step 3: Prepare the Layers

Arrange your materials for the blanket in this order:

  1. Waterproof material (right side down)
  2. Batting (if using)
  3. Top fabric (right side up)

Pin the layers together, starting from the center and working your way out. This prevents shifting during sewing and ensures a smooth finish. Take extra care to smooth out any wrinkles or bubbles between layers.

Step 4: Sew the Layers Together

Using your sewing machine, stitch around the edges, leaving a 5-inch opening on one side for turning. Use a 1/4-inch seam allowance and backstitch at the start and end for security.

Pro tips:

  • A walking foot helps feed multiple layers evenly.
  • Use a 2.5-3 mm stitch length for durability.
  • For hand sewing, use a strong, waxed thread and a backstitch.
  • Consider using a waterproof seam sealer on the stitches for extra protection.

Step 5: Turn the Blanket Right Side Out

Carefully pull the blanket through the opening you left. Use a pencil or chopstick to push out the corners, ensuring they're sharp and well-defined. Take time with this step to achieve crisp edges and a professional look.

Step 6: Close the Opening

Fold the raw edges of the opening inward and pin them in place. Topstitch around the entire blanket about 1/4 inch from the edge. This closes the opening and adds a polished look to your blanket. Consider using a contrasting thread color for this topstitch for an extra decorative touch.

Step 7: Quilt the Blanket (Optional)

For extra durability and to prevent layer shifting, consider quilting your blanket. Try these patterns:

  • Simple grid: Sew straight lines 6-8 inches apart in both directions for a classic look.
  • Diagonal lines: Create a diamond pattern for added visual interest.
  • Wavy lines: Add a touch of whimsy with organic, flowing lines.
  • Custom design: Create a unique pattern that reflects your style or complements the fabric design.

Tips for a Professional Finish

  1. Press as you go: Iron seams flat for a neater appearance and easier sewing.
  2. Choose complementary threads: Match or contrast thread colors with your fabric for a polished look.
  3. Test your waterproof material: Ensure it's suitable for machine sewing to avoid frustration later.
  4. Add extras: Consider attaching ties or a carrying strap for convenient transport.
  5. Reinforce high-stress areas: Add extra stitching to corners and other wear-prone spots for longevity.
  6. Use fabric weights: When cutting slippery materials, use fabric weights to keep them in place for accurate cutting.

Alternative Methods for Making a Waterproof Picnic Blanket

No-Sew Method

Perfect for those without sewing skills or equipment:

  1. Buy a fleece blanket and a vinyl tablecloth of the same size.
  2. Layer the fleece blanket (bottom) and vinyl tablecloth (top).
  3. Use fabric glue or waterproof tape to secure the edges.
  4. Allow 24-48 hours for complete drying before use.
  5. Add decorative elements like fabric paint or iron-on patches for a personal touch.

Waterproofing an Existing Blanket

Give new life to an old favorite:

  1. Select a suitable fabric waterproofing spray.
  2. Thoroughly clean and dry your blanket.
  3. Apply the spray evenly, following product instructions carefully.
  4. Allow 24-48 hours for the blanket to dry completely.
  5. Reapply the waterproofing treatment after every few uses to maintain effectiveness.

Upcycling Options: The Denim Picnic Blanket

Transform old jeans into a unique, durable blanket:

  1. Gather 8-12 pairs of old jeans.
  2. Cut 6.5-inch squares (aim for 121 total).
  3. Arrange squares in a pleasing pattern, incorporating pocket squares for storage.
  4. Sew squares together to form the top layer.
  5. Use a shower curtain liner as the waterproof backing.
  6. Combine the denim top and waterproof backing using the earlier sewing steps.
  7. Add decorative patches or embroidery for a personalized touch.

Caring for Your Waterproof Picnic Blanket

Proper care ensures your blanket lasts for many picnics to come:

  1. Spot clean when possible to maintain waterproofing.
  2. Machine wash gently in cold water when necessary.
  3. Air dry or tumble dry on low heat to prevent damage.
  4. Store in a cool, dry place to avoid mildew.
  5. Reapply waterproofing spray annually or as needed to maintain effectiveness.
  6. Inspect regularly for any tears or wear, and repair promptly to extend the blanket's life.

Enhancing Your Picnic Experience

Take your picnic to the next level with these additions:

  1. Comfortable seating: Bring portable cushions for extra comfort.
  2. Sun protection: Pack a hat or umbrella to stay cool and shaded.
  3. Insect repellent: Keep bugs at bay with natural repellents.
  4. Portable cooler: Ensure your food and drinks stay fresh.
  5. Reusable tableware: Opt for eco-friendly, lightweight plates and utensils.
