I'm always on the hunt for good plain notebooks, and I discovered a stack of perfect 50 page lined notebooks in the $3.00 Daibo store on Queen Street last week. They are a bit smaller than the standard school exercise book and have brown card covers, perfect for embellishment. I'm afraid that I bought all they had in stock, but there are still some unlined ones there for you to buy.
I decorated some with rubber stamps and others with shapes and flowers cut from a couple of rolls of vinyl wallpaper I found in a retro shop on a recent trip to Christchurch.
I hope your own present productions are going well!
