2012 was Queen Elizabeth II's Diamond Jubilee year and London was the home of the Olympic Games, so being patriotic, I made up these fabric covered Union Jack buttons and continue to make them as they are still very popular..
Fabric 100% cotton
Diameter: 18mm / 3/4 of an inch approximately.
Type: Loop / Hole at back to sew onto your garment( back may vary to the picture but will be the same principal)
Pieces: 4 (let me know if you need more but don't want to purchase multiples of 4 to get the desired number)
Pattern: May vary, due to where placed on fabric.
