These snap tabs sew up quickly and are a fun little gift for a D&D group. To that end, they’re available in 5-up and 2-up groupings as well as a single snap tab. The 5-up requires at least a 5×7″ hoop, while the other two fit in a 4×4.
As with other free embroidery patterns here, the SVG file is included in the ZIP package so you can modify it in Inkscape and produce your own variations/sizes/etc.
