This is a very popular thing on UK Scrappers at the moment. It is designed by Tracey at Bubbly Funk - the instructions can be found here.
It uses 24 matchboxes. I got mine from Asda (6 for 31p) so not very expensive to make. I have painted each of the drawers and the front edges of the boxes with blue and purple acrylic paint. I have used Papermania Forever Friends papers, blue and purple bazzill and some Papermania embellishments and brads. I wasn't really sure on how to do the numbers as my handwriting is dire but I was very brave and used the dreaded peel offs - they haven't come out too bad.
They take ages to make but look really good once complete! Now just what to fill it with ...!
