Preparation and Safety Guidelines

Tools Needed
  • Fabric (outer and lining)
  • Batting
  • Button
  • Thin elastic (approx. 1/8 inch wide)
  • Sewing machine
  • Hand sewing needle and thread
  • Fabric scissors
  • Pins or Clips
Safety Guidelines
  • Always use a low-heat setting when ironing near your fabric, especially if using heat-sensitive materials like quilting cotton or fleece. High heat can scorch or melt the fabric.
  • Be mindful of your needle and thread selection. A needle too fine for your fabric might break, while one too thick may cause damage. Choose a needle appropriate for your fabric weight and thread type.
  • Ensure that all raw edges of your fabric are securely enclosed or finished (through turning under or using a zig-zag stitch) to prevent fraying and ensure a durable phone cozy.

Tips

  • Adjust fabric length to fit your phone. Eyeball the size and trim accordingly.
  • Add appliqués or embellishments before the final stitching of the outer fabric.
  • Use clips for bulky layers.
  • Stitch from the inside when sewing a tight curve.

Common Mistakes to Avoid

1. Uneven Seam Allowance

Reason: Inconsistent seam allowance throughout the project leads to a messy, unprofessional-looking finished product. This is especially noticeable in quilting.
Solution: Use a seam guide on your sewing machine or a ruler and rotary cutter to ensure consistent seam allowances.

2. Poorly Matched Fabric Pieces

Reason: Improperly aligning fabric pieces before sewing can result in wonky seams and a less appealing finished cozy. Patterns might not line up correctly, especially with patterned fabrics.
Solution: Carefully pin and align all fabric pieces before sewing, paying close attention to pattern matching and ensuring the edges are smoothly aligned.
