I made 130 wool and silk & wool felted balls and strung them on fishing line with crystals & beads from my stash to make a "curtain." After lots of frustration, I found the perfect needle: the thinest tatting needle you can find. Long enough to go through the felt and fine enough to pass through a 4mm crystal twice.
Cactus monster is a very fun character to make. With a pot and a bunch of wool you can make different monsters and each of them has its unique look and personality. You can also add a bird friend on it! Great project to add something green on your desk and it'll least forever without watering!=) Pot included http://woolbuddy.com/collections/felting-kit/products/needle-felting-cactus-monster-kit
