I've been using paint cards and playing cards as backing for my brooches, and I was also considering using some 1970's recipe cards.
Liz just happened to mention a little tidbit about the busyness of the packaging taking the spotlight away from the actual product - and it was one of those lightbulb moments.
So, after a little bit of re-thinking, I ordered some very white and very plain postcards.
Now my next task is to tone down the look of my market stall..... could be difficult!
