What Is a Pattern Block?

A pattern block, also called a sloper, is a base template for creating your own sewing patterns. It is intended for sewists, pattern makers, fashion designers and students with knowledge of garment construction.

Seam allowances and step-by-step sewing instructions are not included. Add your seam allowances and any design adjustments before cutting your fabric.

Design Features and Pattern Pieces

  • Relaxed workout shorts silhouette.
  • Elasticated waistband.
  • Side pockets.
  • Front shorts piece.
  • Back shorts piece.
  • Waistband piece.
  • Pocket pieces.

What You Will Receive

Your instant download includes 5 PDF files:

  • A4 print file: 16 pages for home printing.
  • US Letter print file: 16 pages for home printing.
  • A0 print file: 1 page for large-format copy-shop printing.
  • Projector file: for use with a home sewing projector.
  • Size chart PDF.

The pattern files include size layers, allowing you to display and print the size you need.

Copy-shop tip: choose the single-page A0 file to avoid assembling tiled A4 or US Letter pages.

Sizes Included

XXS • XS • S • M • L • XL • 2XL • 3XL • 4XL • 5XL • 6XL

Check the size chart in the product images before choosing your size. Body measurements and finished garment measurements are provided in centimetres and inches.

We recommend making a test garment in a similar knit fabric to check the fit before cutting your final fabric.

Recommended Fabrics

This block is designed for knitted fabrics with at least 25% stretch. Choose a fabric with suitable stretch and recovery for comfortable shorts that retain their shape.

Suitable options include stretch jersey, French terry and sweatshirt knits that meet the stretch requirement. Check the stretch of your chosen fabric before cutting; not all sweatshirt fabrics have the same elasticity.

Not designed for non-stretch woven fabrics.

What You Will Need

  • Main fabric: approximately 0.5–1 metre, depending on your size, fabric width and layout.
  • Waistband elastic: approximately 2–3 cm wide.
  • Drawstring cord if you choose to add the drawstring detail.
  • Matching thread and sewing supplies suitable for knit fabrics.

Check your pattern layout and waistband construction before purchasing fabric and elastic, particularly if you adjust the design.

Printing and Projector Guidance

Open the PDF files in Adobe Acrobat Reader on a desktop or laptop computer. Use the Layers panel to select your size before printing.

Print at 100% or Actual Size. Do not select “Fit to Page.” Measure the test square before printing the complete pattern.

A4 and US Letter files require page assembly. The A0 file can be printed at a copy shop, while the separate projector file allows you to project the pattern onto your fabric.
