You can make a bunch of these snowflakes in whatever colors you like and hang them on your tree or adorn your windows and walls.
The size of the motif depends on the thread or yarn and the hook you are going to use. I crocheted my Crochet Pineapple Snowflake with cotton thread size 5 and a 2,5 mm crochet hook. The finished snowflake measures almost 12 cm (about 4,6 inches) in diameter.
Besides your thread and hook, you will also need a needle to weave in loose ends and a pair of scissors, as well as white school glue or your favorite starch, stainless steel pins, plastic wrap and some kind of blocking board in order to block your snowflakes.
