No matter if you love them for the variety of Sugar Skull (Alfeñiques), in Mexican celebration (Día de Muertos) or the Roman Catholic holiday (All Souls' Day), everyone loves a unique design!
This one will require twisted wire work to create the the webbed overlay, and you can either create the spiders with glass, or form them separately with solder around the colored glass in the black widow's butt, and add them on top of the glass later.
The pattern will print in an exploded view, so you will have templates for each section.
