How to Use the Deco Tumbler Ruler for Quilting

Quick Answer

To use the Deco Tumbler ruler, align it on your fabric, cut with a rotary cutter, and piece the curved seams carefully. Start with simple projects like the Posh Gobble pattern to practice, and always test on scrap fabric first.

The Deco Tumbler ruler is a versatile tool for creating beautiful curved quilt blocks. Unlike traditional rulers, it features a gentle curve that adds movement and elegance to your quilts. Whether you're a beginner or an experienced quilter, mastering this ruler opens up a world of creative possibilities.

In this guide, we'll walk you through the essential techniques for using the Deco Tumbler ruler, from cutting to piecing. You'll also learn common mistakes to avoid and get tips for achieving crisp, professional results.

Getting Started with the Deco Tumbler Ruler

Before you begin, gather your materials: the Deco Tumbler ruler, a sharp rotary cutter, a cutting mat, and fabric. The ruler is designed to work with specific pattern requirements, so always check the pattern's material list. For example, the Posh Gobble pattern calls for 7 fat quarters for feathers and a QCR Mini Ruler, but the Deco Tumbler ruler can be used similarly for curved cuts.

Start by washing and pressing your fabric to prevent shrinkage. Place the fabric on the cutting mat with the fold aligned. Position the ruler on the fabric according to the pattern's instructions. The curved edge should face the direction you want to cut. Hold the ruler firmly and cut along the curve with even pressure.

• Always use a new, sharp rotary blade for clean cuts.
• Press seams with a hot, dry iron to set curves.

Cutting Techniques for Perfect Curves

When cutting with the Deco Tumbler ruler, accuracy is key. Align the ruler's markings with the fabric's grain line to ensure consistent pieces. For best results, cut slowly and keep the ruler steady. If you're new to curved cutting, practice on scrap fabric first to build confidence.

A common mistake is rushing the cut, which can cause fabric shifting. To avoid this, apply firm pressure on the ruler with your non-dominant hand and cut away from your body. For multiple pieces, stack fabric layers carefully and use a rotary cutter with a sharp blade to prevent dragging.

• Use a mat with grid lines for accurate alignment.

Piecing Curved Seams

Piecing curved seams can be tricky, but with practice, it becomes second nature. Start by pinning the convex and concave pieces together at the center and edges. Use a scant 1/4-inch seam allowance and sew slowly, removing pins as you go. Press the seam toward the darker fabric to reduce bulk.

A common pitfall is not pinning enough, leading to puckered seams. To ensure smooth curves, use more pins than you think necessary, especially around the curve's apex. If you notice distortion, rip out the seam and try again—it's better to redo than to settle for a wavy block.

• Test your seam allowance on scrap pieces before starting.

Troubleshooting Common Issues

If your blocks aren't coming out perfectly, check your cutting accuracy. Misaligned cuts can cause pieces not to fit together. Also, ensure your seam allowance is consistent. If you're having trouble with fabric stretching, try using a walking foot or starching your fabric beforehand.

Another issue is not squaring up your blocks after piecing. Use a square ruler, like the Sew Square 4 from Sew Kind of Wonderful, to trim your blocks to the correct size. This ensures your quilt top goes together smoothly.

• Keep a seam ripper handy for quick fixes.

Step-by-Step: Using the Deco Tumbler Ruler

1. Prepare Your Fabric: Wash, dry, and press your fabric. Cut strips according to your pattern's requirements, ensuring they are wide enough for the ruler's curve. Checkpoint: Fabric should be wrinkle-free and grain-aligned.
2. Align the Ruler: Place the Deco Tumbler ruler on the fabric, aligning the marked lines with the fabric's straight edge. Ensure the curve is positioned where you want the cut. Common mistake: Misalignment causes uneven pieces. Double-check before cutting.
3. Cut with Precision: Hold the ruler firmly and cut along the curved edge with a rotary cutter. Use smooth, even strokes and apply consistent pressure. Checkpoint: Cut edges should be clean and free of fraying.
4. Pin and Sew: Pin the curved pieces together, matching the centers and ends. Sew with a 1/4-inch seam allowance, removing pins as you go. Press seams to one side. Common mistake: Insufficient pinning leads to puckers. Use extra pins for curves.
5. Square Up Your Block: After piecing, trim your block to the required size using a square ruler. This ensures your quilt top pieces fit together accurately. Checkpoint: Block should be perfectly square and meet pattern dimensions.
