DIY Guide Sew Envelopeclosure Pillowcases to Prevent Slipping

Commercial pillowcases often disappoint with uncomfortable fabrics or poor designs that quickly lose their shape. This simple guide will teach you how to sew a pillowcase with an inner flap that securely holds your pillow in place while allowing you to choose fabrics that suit your personal style.

Selecting quality materials is crucial for creating a comfortable, durable pillowcase. Here's what you'll need:

• Cotton: Breathable, moisture-wicking, and suitable for year-round use
• Linen: Naturally eco-friendly with excellent breathability (may wrinkle easily)
• Silk: Luxuriously soft but requires delicate care
• Jersey Knit: Stretchy and exceptionally comfortable
• Flannel: Ideal for winter with superior warmth

Tip: Beginners should start with cotton or linen fabrics that are easier to work with.

• Sewing machine (optional - hand sewing works too)
• Sharp fabric scissors
• Measuring tape or ruler
• Needles and thread
• Pins for fabric placement
• Iron for pressing seams
• Fabric marker or chalk

Accurate measurements ensure your pillowcase fits snugly. For a standard 48cm × 74cm pillow:

1. Measure your pillow: Record exact length and width
2. Calculate main fabric: Add 1cm seam allowance to each side (50cm × 76cm)
3. Determine flap size: Cut two pieces measuring 50cm × 26cm (including 1cm seam allowance)

Cut all fabric pieces according to your measurements. Ensure straight edges and clean cuts.

Fold and press the long edges of both flap pieces inward twice (1cm each fold) to create clean hems. Secure with pins and stitch.

With right sides together, align flaps at opposite ends of the main fabric. Pin all edges securely before stitching around the perimeter with a 1cm seam allowance.

Trim seams to 0.5cm and clip corners diagonally (avoiding stitches). Turn right side out, push out corners gently, and press thoroughly.

• Reinforce corners and flap openings with additional stitching
• Consider decorative elements like embroidery or lace trim
• Match thread color closely to your fabric

To maintain your handmade pillowcase:

• Wash weekly with mild detergent
• Line dry away from direct sunlight
• Iron while slightly damp for crisp results
• Store in dry, well-ventilated areas

Once you master the basic technique, explore these creative options:

• Reversible designs: Combine seasonal fabrics
• Patchwork styles: Mix patterns and colors
• Children's versions: Use playful prints

This customizable pillowcase solution combines practicality with personal expression, transforming your sleep experience one stitch at a time.
