TurtleStitch is freely available software that enables the generation and stitching of patterns using a digital embroidery machine. It gives programmatic control of the machine, enabling a wide range of patterns to be designed and stitched onto fabric. It was developed by Andrea Mayr-Stalder, and runs in a browser window.

TurtleStitch is used in WMG for outreach activities, as a means of raising awareness of the breadth of engineering. The WMG Outreach team has created a number of resource cards to support its use, including maths task cards suitable for upper key stage 2. Children work out the answers to maths questions and check them using Turtlestitch.

To print the full sets of cards, we recommend setting your printer to print landscape on both sides and flip on short edge. For enquiries about the cards or to report an error, please email
