This is my button-hole from our Daughter's wedding a couple of years ago. Carole has already posted Fiona's bouquet and explained that as she is allergic to real flowers, everything on the day was faux, which is why this is looking in such good condition.
Thankfully for this challenge, Fiona's colour scheme was purple, but I'm really not sure I'll find anything else around the house from that lovely day to use in the coming Saturday's.
