Last month i ordered a DIY kit from Growing Books. In the kit you get everything you need minus the plant (those cannot be posted). You can select your colour combinations on the website and they select books to match - or email if there's a colour combination you'd like. There is also option to add a candle.
Purchase a succulent from local nursery, Bunnings or Masters. Or you may already have some growing in garden and could cut some off.
I ordered this one for a friend's birthday present. She absolutely loves books and this will look lovely in her library.
The 'white' candle looked a bit purple against the colours of the books so i purchased a creamy white one instead.
You can purchase yours from Growing Books website or if you live in NSW they are often at The Olive Tree Market and Bondi Markets.
Im really fussy with colours and book titles so Julian and I have collected some old hardcover books in nice titles and colours and going to attempt to make our own for our home. We are thinking of putting a bonsai in one for the study.
