Preparation and Safety Guidelines

Tools Needed
  • Fabric backing
  • Batting (polyester or cotton)
  • Quilt top
  • Painter's tape
  • Basting spray (optional)
  • Safety pins (optional)
  • Embroidery thread (for hand quilting)
  • Hand needle (for hand quilting)
  • Sewing machine (for machine quilting)
  • Walking foot or free-motion foot (for machine quilting)
  • Fabric chalk/pencil/marker (optional)
Safety Guidelines
  • Always work on a clean, flat surface to prevent wrinkles and shifting of layers. Use a large, clean floor or a table big enough to accommodate your entire quilt.
  • Ensure your batting is completely smooth and free of wrinkles before layering. Wrinkles will show through in your finished quilt.
  • Use plenty of safety pins or basting spray to secure your quilt layers together. Insufficient pinning can lead to shifting during quilting, resulting in puckers and uneven stitching.

Tips

  • Use cotton batting for easier handling and a more popular choice among quilters.
  • When spraying basting spray, maintain a distance of about 12 inches to avoid over-saturation and ensure even distribution.
  • For machine quilting, use a stitch length between 2.5 and 3, adjusting based on quilt size. Begin quilting from the center and work outwards.

Common Mistakes to Avoid

1. Uneven Layers

Reason: Inconsistent fabric smoothing or pulling during layering can lead to wrinkles and puckers, especially noticeable in the final quilt.
Solution: Carefully smooth each layer, working from the center outwards, and use basting spray or pins to secure the layers evenly.

2. Incorrect Fabric Orientation

Reason: Failing to align the backing, batting, and top fabrics properly before basting can result in mismatched patterns or skewed blocks.
Solution: Ensure all fabrics are aligned at the edges and corners before basting, using a ruler and pins to maintain accurate placement.

FAQs

What's the best way to prevent wrinkles and puckers in my quilt sandwich?
Smooth out each layer meticulously before layering. Use a large, flat surface and a quilting ruler to ensure everything is even. Consider using basting spray to temporarily hold the layers together, working in smaller sections to minimize wrinkles. Finally, ensure your batting is appropriately sized to avoid pulling and stretching during quilting.
