Riley Blake Diamonds Quilt Pattern by Lila Tueller – Free Downloadable PDF

The Riley Blake Diamonds pattern is a free downloadable PDF designed by Lila Tueller for quilters who want to create a striking, on-point diamond-style quilt. The finished quilt measures 62¾" x 79", making it a generous lap or throw size that works beautifully as a bed accent or statement piece for any room. This pattern is published by Riley Blake Designs and is built around their fabric collections, giving quilters a cohesive, coordinated color story straight from the cutting table.

About the Design

The quilt is constructed using 9½" x 9½" finished blocks set on the diagonal, which is the hallmark of the classic "on-point" or diamond setting. This layout gives the quilt its namesake diamond visual effect, where square blocks are rotated 45 degrees and separated by sashing and posts. Setting triangles fill in the angled edges of the quilt center, while corner triangles complete the four corners before borders are added. The result is an elegant, dynamic surface that feels more complex than its construction actually demands.

According to the pattern, a basic knowledge of quilting technique and terminology is required, placing this project at an intermediate beginner to intermediate skill level. Quilters who are comfortable with straight-line piecing, diagonal settings, and adding borders will find this pattern approachable and rewarding.

Techniques Used

• On-point / diagonal block setting – Blocks are sewn together in diagonal rows rather than straight rows, creating the diamond arrangement that defines the quilt's overall look.
• Sashing and posts – Sashing strips separate individual blocks, and small post squares sit at the intersections of the sashing, adding structure and visual interest to the quilt center.
• Setting triangles and corner triangles – These are cut intentionally larger than needed and then trimmed after assembly to square up the quilt center, ensuring a clean ¼" seam allowance on all sides before borders are attached.
• Bordered quilt construction – Two separate borders frame the quilt center. Side borders are always sewn on before top and bottom borders, a standard quilting practice that ensures flat, even results.
• Measuring through the quilt center – The pattern specifically instructs quilters to measure through the center of the quilt before cutting border pieces, a best-practice technique that compensates for any variation in seam allowances accumulated during piecing.
• Layering, batting, and binding – The quilt is finished in the traditional method: quilt top, batting, and backing are layered together, quilted, and then bound around the edges.

Stitches and Sewing Basics

• ¼" seam allowance – All measurements in the pattern include a standard ¼" seam allowance, the universal quilting seam.
• Right sides together (RST) – All pieces are sewn with right sides facing each other unless the pattern specifically states otherwise, a fundamental quilting convention.
• Straight-line piecing – The blocks, sashing, and borders are all assembled using straight seams, keeping the construction manageable even within the more visually complex diagonal setting.

Materials and Fabric Requirements

This pattern is designed specifically around Riley Blake Designs fabrics, and the fabric requirements are clearly outlined for a coordinated finish.

• 1 Halle Rose 10-inch Stacker (10-4180-18) – A pre-cut bundle of 10" x 10" squares. Each square is used as a Center Block in the on-point setting, making this pattern an ideal project for showcasing a pre-cut collection.
• 1¼ yards of gray floral (C4181 Gray) – Used for Border 2. The pattern calls for 7 strips cut at 5½" x width of fabric (WOF), which are sewn end to end to achieve the required border lengths: 69½" for side borders and 63¼" for top and bottom borders.
• 1⅜ yards of snow white shade (C200-03 Snow White) – Cut into 2½" WOF strips, then sub-cut into squares used for sashing posts or other quilt center components.
