Rainbow Burst Quilt

Rainbow Burst Quilt Pattern by Cait Lisle Designs

The Rainbow Burst Quilt is a stunning 48" x 48" square quilted throw designed by Cait Lisle Designs. True to the designer's signature style, this pattern takes a traditional piecing approach and gives it a fresh, modern twist, resulting in a vibrant, eye-catching design that celebrates color in a bold, graphic way. As a beginner-friendly, downloadable PDF pattern, it is an excellent choice for those new to quilting as well as experienced quilters looking for an enjoyable, satisfying make.

Two Designs in One

One of the most exciting features of the Rainbow Burst Quilt pattern is that it includes two distinct layout options within a single purchase. Both layouts use the same core construction techniques and fabric requirements, but produce noticeably different visual effects depending on how the blocks are arranged. This gives quilters the flexibility to choose the look that best suits their style, their fabric collection, or the intended recipient of the finished quilt.

• Layout Option 1 — presents the rainbow color arrangement in one configuration, creating a particular burst or radiating effect across the quilt surface.
• Layout Option 2 — rearranges the same color elements to produce an alternative visual composition, offering a fresh take without requiring any additional skills or materials.

Having two designs in one pattern represents excellent value, and quilters who enjoy making multiples will appreciate being able to produce two distinctly different quilts from the same set of instructions.

What Is Being Made

The finished project is a quilted throw measuring 48 inches by 48 inches, making it a versatile square blanket suitable for use as a lap quilt, a decorative wall hanging, a baby quilt, or a cozy accent throw for a sofa or bed. The rainbow color palette — spanning pink, red, orange, yellow, light green, dark green, light blue, dark blue, purple, and a white background — gives the finished quilt a cheerful, energetic personality that works beautifully in children's rooms, modern interiors, or as a celebratory gift.

Quilting Techniques Used

The Rainbow Burst Quilt is built around traditional patchwork piecing techniques, which involve cutting fabric into precise geometric shapes and sewing them together to form a larger, cohesive design. Cait Lisle Designs is known for applying these time-honored methods in ways that feel contemporary and accessible, and this pattern is a clear example of that philosophy.

Key Techniques Include:

• Rotary cutting — fabric is cut into strips and squares using standard quilting measurements, with Width of Fabric (WOF) strips cut from the background fabric as a starting point.
• Precise seam allowances — a consistent ¼" seam allowance is used throughout the entire pattern, which is the standard in quilting and essential for blocks to align correctly.
• Pressing seams — the pattern includes directional pressing guidance, with arrows indicating which direction seams should be pressed to reduce bulk and ensure flat, accurate piecing.
• Block construction and layout — individual pieced blocks are assembled and then arranged according to either Layout Option 1 or Layout Option 2 to create the overall Rainbow Burst design.
• Quilt finishing — the pattern covers the complete quilt-making process through to a finished quilt, including the addition of backing fabric, batting, and binding.

Scrap and Fat Eighth Friendly

The Rainbow Burst Quilt is specifically designed to be fat eighth and scrap friendly, which is a significant advantage for quilters who maintain a fabric stash. Most of the rainbow colors require only one Fat Eighth (18" x 11") of fabric each, meaning this pattern is an ideal stash-buster. Quilters can pull from existing collections of scraps, provided each piece used measures at least 5¼" square, making it a practical and economical project.

Stitches and Sewing Methods

As a quilting pattern, the Rainbow Burst Quilt is sewn on a sewing machine using a standard straight stitch. The consistent ¼" seam allowance is maintained throughout all piecing stages. Hand quilting or machine quilting through
