I made these snowflakes for my Christmas tree and they are so easy.
You just need wire and any beads you like. You could even use thin pipe cleaners.
For the first beads strung on it’s best to use hearts like these Because they fit better together than round beads and will sit nicely. The rest is up to you. You could use tear drops, round beads, star beads, anything. On the end you could glue the last bead or you could use bead stops, which is what I have done in the picture.
