For the base I added a book box I had lying around, you could probably add any small rectangle box though.
Next I started layering open spined books. It was a good idea to add a few hardback books to give support wherever possible because they help achieve the tree shape.
Simply add the books in ascending order and then string on some fairy lights and a few ornaments if you want to accessorise some more. I made 2 versions but eventually went back to the more minimalistic version because that’s more my style.
Let me know if you try this! Happy Holidays everyone!!
