Quick Answer
To use 72 degree diamonds in EPP, choose the right paper size and seam option, baste each piece accurately, then join the sharp points with precise stitching to form crisp quilt blocks.
Why 72 Degree Diamonds Work in EPP
The 72 degree angle is a common building block in geometric quilt designs, often appearing in star patterns and tessellations. Because the angle is sharp, it creates striking visual effects but also demands careful handling at the points.
Understanding the geometry helps you plan your seam allowances and basting method. The 72 degree diamond's narrow points can be tricky to fold neatly, so a little extra care during preparation goes a long way.
Choosing the Right Paper Size and Seam
Paper Pieces offers 1-1/2" 72 Degree Diamonds in various pack sizes and seam options. The seam option determines how much fabric wraps around the paper: 1/4" seam is standard for most projects, while 3/8" seam provides a larger allowance for thicker fabrics or beginners.
Windowed papers have a cut-out center, allowing you to see the fabric right side, which can help with pattern matching. No-seam papers are used for foundation piecing or when you want to remove the paper before stitching.
Consider your project scale: small packs (66 pieces) are great for a single block, while large (396) or bulk (792) packs suit bigger quilts or multiple projects.
Basting and Folding Sharp Points
The most common challenge with 72 degree diamonds is getting the points to lie flat. When basting, fold the fabric over each edge, and at the point, take a small tuck to avoid bulk.
Use a glue stick or thread basting—whichever you prefer—but ensure the fabric is taut and the paper stays flat. A common mistake is pulling too tightly, which warps the diamond shape.
If you're using windowed papers, you can check that your fabric pattern is centered before basting, which is especially useful for directional prints.
Step-by-Step: Using 72 Degree Diamonds in EPP
- Select Your Paper and Seam Allowance: Choose the 1-1/2" 72 Degree Diamond paper size and seam option that fits your project. For most quilting, a 1/4" seam works well; for thicker fabrics or beginners, consider 3/8". If you need to match patterns, use a windowed version. Check that your fabric thickness matches the seam allowance you picked.
- Cut Your Fabric with Adequate Margin: Cut fabric pieces large enough to cover the paper plus the seam allowance. A common mistake is cutting too small, which leaves gaps at the points. Add at least the seam allowance on all sides, plus a little extra for safety. When in doubt, cut larger—you can trim later, but you can't add fabric back.
- Baste Each Diamond: Place the paper on the wrong side of the fabric and baste using your preferred method (thread, glue, or clips). Fold the fabric over each edge, and at the sharp points, make a neat tuck to reduce bulk. Keep the paper flat and the fabric smooth. Check that all points are covered and the paper is not bent before you move on.
- Arrange Your Diamonds for the Block: Lay out your basted diamonds in the desired pattern. For a 72 degree diamond, common arrangements include star points or tessellating rows. Ensure that the angles align correctly to create the intended design. Take a photo of your layout so you can reference it when stitching.
- Join the Diamonds with Whipstitch or Flat Stitch: Place two diamonds right sides together and stitch along one edge using a whipstitch or flat stitch. Start and stop at the paper edges, and be careful at the points—make sure the stitches are secure but not too tight, which can cause puckering. Check that the points meet neatly; if they don't, adjust your seam placement.
- Press and Remove Papers: Once all pieces are joined, press the seams flat. Then carefully remove the papers. If you used windowed papers, removal is easier because you can see the stitches. For sharp points, use a gentle pull to avoid tearing the fabric. If you plan to quilt through the block, you may leave the papers in until after quilting.
