What is a Sewing Pattern?

To begin with, let’s talk about what a sewing pattern is. A sewing pattern is your blueprint for creating a variety of sewn items, whether that’s a dynamic pair of shorts, an elegant dress, or an intricate quilt. It provides you with vital information, including the size chart, garment description, and detailed step-by-step instructions. Each pattern is composed of paper templates that guide you on how to cut fabric pieces into specific shapes and sizes.

The beauty of using a sewing pattern lies in its ability to offer various design variations as well as different types and sizes.

How to Read a Sewing Pattern: Envelope Front

Now it’s time for you to learn how to read a sewing pattern. A pattern envelope contains four sections: the front envelope, the back envelope, inside the envelope, and common sewing symbols. Let’s start by reading the front of the pattern.

Pattern number or pattern name

Each sewing pattern has a unique identifier known as the pattern number or name. This key detail helps you locate and reference your chosen design when purchasing materials or discussing your project with others.

Often listed at the top of a pattern envelope, this label distinguishes between different styles offered by sewing pattern companies.

Model pictures

Model pictures on the front envelope give you a sneak peek into how your finished garment can look. These pictures provide a visual representation of the different design variations you can achieve with the same pattern.

By observing these model pictures closely, you’ll gain inspiration for your own project. You can also learn about potential changes and enhancements suitable for your chosen fabric type and personal style.

Sizing

Many sewing patterns come in multiple sizes. Unlike ready-to-wear clothes, pattern sizes are determined by your body measurements and not assigned numerical labels.

It can puzzle beginners when their usual size doesn’t align with the pattern’s size chart. For an accurate fit, diligently compare your body measurements against those provided on the envelope’s back.

Sewing level

Sewing patterns often indicate a sewing level. This is a helpful guide that tells you how easy or challenging the project will be. It’s important to choose a pattern that matches your skill level to avoid frustration.

Some patterns are labeled as “beginner” or “easy,” while others may be marked as “intermediate” or “advanced.” Take note of these labels when selecting your pattern, so you can feel confident in tackling the project based on your current sewing abilities.

The small description gives you several suggestions for the garment project to help you better learn how to read a sewing pattern.

Fabric suggestions

Fabric suggestions can help you choose the right fabric for your project. These suggestions may include specific types of fabric that work well with the pattern. They may also specify the weight or thickness of fabric suitable for the design.

The suggestions may even offer guidance on prints or patterns that complement the design of your garment. So be sure to check them out before starting your sewing project!

Fabric requirements

Fabric requirements indicate the amount of yardage you’ll need to complete your garment. The size and pattern option you choose will determine how much fabric you need. You’ll find a table on the envelope indicating the required yardage for different fabric widths.

Notions

Notions are the small tools and accessories that you’ll need to complete your sewing project. Some common notions include buttons, zippers, thread, pins, and elastic. It’s important to have all your notions ready before you start sewing so that you don’t run into any delays along the way.
