For the big flowers in the corners (which double as photo corners) I used only brads and...pronto!
The photo is not glued, it stays in place with the flowers - "photo corners", so I can change it an a second. The fridge was never so pretty!
For the back, I glued the magnet in place and then covered the whole with white self adhesive matstack.
The possibillities are endless, I'm already thinking about making another with floral swirls...
