Start by cutting a long piece of wire. Shape it into a large spiral by wrapping it around a circular object, making sure it gets smaller as you go up. This will form the base structure of your Christmas tree.
Using your crochet thread, wrap it tightly around the wire spiral, starting from the bottom and working your way up. For a clean and even look, make sure the crochet thread is tightly wound around the wire without gaps.
Once you've finished wrapping the wire, glue small pearls at random spots along the spiral.
Use a small wooden or plastic star to top the tree. Then secure it to the top of the wire frame using hot glue, making sure it stands straight and firmly attached.
Once the glue has dried, place your knitted spiral Christmas tree anywhere in your home.
