The Konigi DIY Wireframe Magnet Kit is based on the wireframe stencils and includes 3 sheets of elements that might be useful in whiteboard prototyping. Simply download and print the PDFs onto magnet sheets. They were designed and tested for use with Avery 3270 Printable Magnet Sheets for Inkjet Printers. Lamination is also recommended so they're usable with dry-erase markers. Enjoy!
