TOOLS
Freezer Paper
The best pattern paper. Iron on a wool setting and it sticks to fabric. Reusable, durable, and transparent enough for tracing.
Tracing Wheel
Spokes aren't too sharp and it works well to trace a temporary line on fabric or paper.
Wavy Rotary Blade
Use in place of pinking shears, quickly trim outside edges of circles.
