What Is a Rotary Cutter and What Is It Used For?

A rotary cutter is a handheld tool with a circular blade that rotates as you glide it forward. It’s commonly used in:

• Sewing and quilting
• Crafting and scrapbooking
• Pattern making
• DIY vinyl cutting
• Leather, felt, or foam trimming

Why use one? Compared to scissors, rotary cutters provide straighter, more consistent lines—especially on fabric. They’re also much faster when cutting multiple layers.

How to Use a Rotary Cutter for the First Time

If you’re a beginner, here’s a step-by-step on how to start using a rotary cutter confidently:

Step 1: Gather Your Tools

• Rotary cutter (choose 28mm, 45mm, or 60mm depending on the material)
• Self-healing cutting mat
• Acrylic ruler
• Fabric or material you want to cut

Step 2: Prep Your Cutting Area

• Place your cutting mat on a flat, stable surface
• Lay your fabric smooth and flat on the mat
• Use fabric weights or clips if needed to avoid shifting

Step 3: Align and Cut

• Place the acrylic ruler over the cut line
• Hold the ruler down firmly with your non-dominant hand
• With your dominant hand, hold the rotary cutter upright and push it forward along the edge of the ruler
• Apply even pressure throughout the motion

Safety Tip: Always close or lock the blade after every use.

How to Use a Rotary Cutter and Ruler for Straight Lines

Using a rotary cutter and ruler together is essential for accurate, clean cuts—especially for quilting or cutting multiple fabric strips.

Tips:

• Use a non-slip ruler or add grip stickers underneath
• Align fabric with gridlines on the mat
• Press the ruler down firmly
• Keep the rotary cutter blade flush against the ruler’s edge
• Cut in one fluid motion without lifting the blade midway

How to Use a Rotary Cutter with Patterns and Templates

Using a rotary cutter with templates saves time and improves accuracy. Here’s how:

1. Secure the pattern to the fabric with pins or pattern weights
2. For straight edges, line up your ruler over the pattern edge
3. For curves, use a smaller rotary blade (28mm or 18mm) and guide slowly by hand
4. Cut just outside or directly on the pattern line, depending on your seam allowance

Pro Tip: Don’t try to cut around pins—use weights instead.

How to Use a Rotary Cutter and Mat the Right Way

A self-healing cutting mat is crucial. Here’s why:

• Protects your table
• Preserves your blade
• Offers measurement guides for precision

How to use the mat effectively:

• Align fabric edges with the printed grid
• Use the lines to square corners and ensure even cuts
• Rotate the mat, not the fabric, when cutting at tricky angles

How to Replace a Rotary Cutter Blade (Step-by-Step)

Dull blades lead to frayed edges, skipped cuts, and frustration. Here’s how to change yours safely:

1. Open the rotary cutter and unscrew the bolt or knob
2. Remove the old blade (use gloves or a cloth to protect your fingers)
3. Place the new blade in the same position and orientation
4. Reassemble in reverse order and tighten
5. Do a test cut before returning to your project

Dispose of old blades safely in a blade-safe container or sharps box.

FAQ: How to Use a Rotary Cutter

Do you push or pull a rotary cutter?

Push the rotary cutter away from your body. Pulling can lead to uneven cuts or loss of control.

What can you do with a rotary cutter?

Rotary cutters are incredibly versatile. Use them for:

• Quilting and piecing fabric
• Cutting multiple fabric layers
• Trimming paper and cardstock
• Shaping leather or felt
• Vinyl and decal trimming

What’s the best rotary cutter size for beginners?

A 45mm rotary cutter is the most versatile and beginner-friendly. It works well on fabric, paper, and felt and handles both straight lines and gentle curves.

How often should I change the blade?

Change your rotary cutter blade when:

• Cuts start skipping
• Fabric snags or frays
• You need multiple passes to cut cleanly
• You hear a “dragging” sound as you cut

For frequent use, change every 1–2 months.

Can I cut paper with my fabric rotary cutter?

While you can, it’s best to dedicate one blade for paper and another for fabric. Cutting paper will dull blades much faster.
