Below is a beginner's guide for sewing sweatpants. 



1. Choose the Appropriate Material

Fabric & Thread
There's a few considerations when choosing your fabric for sweatpants:

  • Quality of fabric to prevent pilling
  • Desired level of warmth and stretch

The most commonly used fabric for sweatpants is sweatshirt fleece, also known as brushed fleece. The Sweatpants DIY Kit come with high quality poly cotton fleece to match the Boxy Hoodie DIY. 

As per the Glory Allan pattern, here is the fabric required for sewing sweatpants:

Fleece Fabric: 2.75 yards (2.51 meters)

1.50" Elastic: 2-4" less than your waist measurement 

0.75" Elastic: 8-14" (optional for elastic cuff, tapered leg opening)

Rib Knit: 0.25 yards (0.23 meters; optional for rib knit, tapered leg opening)

All Purpose Polyester Thread: 100 yards minimum


2. Wash the Fabric

A general rule for every sewing project is to wash the fabric before construction. This helps pre-shrink it and set the dye. All cotton products will have natural shrinkage, so it's best to take the safe route. 

Remember to:

  • Unfold the fabric before loading in the machine
  • Don't overcrowd the machine
  • Wash like you would wash the final pants
