These buttons to cover have a diametre of 15mm. They can be covered with fabric rounds measuring 30mm diametre.
The buttons are extremely simple to assemble: simply place the fabric right side down on a table, place the domed part of the button on top and, with your two thumbs, pull the overlaying fabric towards the inside of the button. Press around the edge of the button so that the fabric catches on the small teeth. Clip on the back part of the button, a small "pop" ensures that you have fixed the two parts together correctly.
