These Eyelets are the same ones we use on our flatwork and on our pré assembled bobbins. It speaks for itself that our flatwork was designed around these and make for a perfect fit.
To set the eyelets we recommend using a press or a hammer in combination with the stewmac eyelet setting tool. Other methods might work as well, but this is the one we use and can guarantee it's success.
