Large replica shawl pin
These large shawl pins are designed to replicate celtic designs. They're made of metal with a connected centre pin.
The grey has a dull finish like iron, while the gold has a bright and shiny finish. These are the most pointy of all the replica shawl pins, so I wouldn't recommend them for extremely delicate yarns just in case they snag.
These pins are 6cm wide, with a 6cm centre pin. They would work well for all many yarn weights, up to bulky yarn.
