Circular Bag Pattern Generator

Marking out and drawing accurate circles is always a struggle, so use this pattern generator to draw the circles for you!

Marking out and drawing accurate circles is always a struggle, so use this pattern generator to draw the circles for you! It tiles the circle across multiple pages if required so it should work with any size circle and seam allowance you need.

Perfect for gym bags, stuff sacks, barrel handlebar bags etc.

Simply cut along the marked margin border of the paper, tape the pages together, and then use the complete pattern for your projects! Make sure to print at 100% scale (or "Actual Size") and measure the diameter of the inner circle to confirm it has printed accurately (Diameter = Radius × 2).
