Riley Blake Baby Geo Quilt Pattern – Free Downloadable PDF by The RBD Designers

The Riley Blake Baby Geo is a striking geometric baby quilt pattern designed by The RBD Designers for Riley Blake Designs. Available as a free downloadable PDF, this pattern produces a finished quilt measuring 48" x 48" — a perfect square size for a baby quilt that works equally well as a crib topper, play mat, or a cherished handmade gift for a newborn. The design is rated intermediate in difficulty, making it an excellent next step for quilters who are comfortable with basic patchwork and are ready to explore more dynamic, angular piecing.

What Is Being Made

The Baby Geo pattern creates a bold, eye-catching quilt built entirely from triangular fabric pieces arranged in a repeating geometric layout. The overall effect is a lively, mosaic-like surface full of movement and color, characteristic of the modern quilting aesthetic that Riley Blake Designs is known for. The 48" x 48" finished size is intentionally scaled for baby use, though the graphic, contemporary look means it could easily serve as a decorative lap quilt or wall hanging as well.

Fabric and Materials Required

This pattern is fabric-forward, relying on a carefully curated selection of prints or solids to bring the geometric design to life. The materials needed include:

• Triangles: ¼ yard each of 13 different fabrics — the variety of fabrics is central to the design's visual appeal, creating contrast and rhythm across the quilt surface
• Binding: ½ yard of fabric to finish the quilt edges cleanly
• Backing fabric and batting (standard quilt finishing materials, to be selected by the quilter)
• Basic quilting supplies including a rotary cutter, cutting mat, quilting ruler, and sewing machine capable of an accurate ¼" seam allowance

The use of 13 different fabrics gives quilters a wonderful opportunity to showcase a fabric collection, use coordinating prints from a single Riley Blake Designs fabric line, or pull from a scrappy stash of beloved remnants. Fat quarter bundles or precut collections can be an efficient starting point for fabric selection.

Cutting Instructions and Template Use

One of the defining features of this pattern is the use of a custom triangle template included in the PDF. Accurate template cutting is essential for a pattern like this, where every piece must align precisely for the geometric design to read correctly across the quilt top.

• Cut one 7" strip selvage to selvage from each of the 13 fabrics
• Use the provided triangle template to cut 12 triangles from each of the 13 fabrics, yielding a total of 152 triangles for the main quilt body
• Cut an additional 16 edge triangles from assorted triangle fabrics to finish the outer edges of each row cleanly

The inclusion of dedicated edge triangles is a thoughtful design detail — these pieces fill in the zigzag perimeter created by the triangular layout, resulting in straight, even quilt edges that are easy to bind.

Techniques and Construction Method

The Baby Geo pattern is constructed using a row-based assembly method, which is a reliable and organized approach for quilts with repeating geometric units. The technique involves building individual rows first, then joining the rows together to complete the quilt top — a method that helps manage accuracy and alignment throughout the process.

Row Construction

• Lay all triangles out in 8 rows of 19 triangles each, with edge triangles placed at both ends of every row
• Stitch triangles together in pairs first, carefully maintaining the ¼" seam allowance throughout — precision here is critical when working with bias-cut triangle edges, which can stretch if handled carelessly
• Press seams after each stitching step to keep units flat and accurate
• Continue joining pairs into larger sets, pressing after each seam, until each full row is complete
• Repeat the process to construct all 8 rows
