Yes another box collector here. My family laugh at me but guess who they come to when they need a box? Thinking about it I have upended shoe boxes on shelves and in cupboards keeping CDs, DVDs and books tidy. Children's crayons, pencils felt tips etc in another shoe box with lid Colouring, puzzle and drawing books in a cardboard box under an occasional table. Wardrobe shelves and drawers have socks, scarves, tights, knickers etc neatly kept together in a variety of cardboard boxes. Oh yes shoes and trainers in the bottom of the wardrobe also in boxes. Ice cream boxes are used for lunches, keeping buns and biscuits in and also water colour blocks and paint brushes. Sewing stuff , buttons, zips, cotton reels also kept in old sweetie tins.
I have also found the perfect place for hiding sweets and chocolates ... a big 'Roses' tin. No one ever expects actual goodies in a sweetie tin!!!!
