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.

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.
