All items were made and designed by me using my Clover Soft Touch US Size E (3.5 mm) hook, and stuffed using polyester fiberfill. Some of the crochet patterns which I used here are available online, and I have included links where applicable. Some patterns have not yet been released. :)

Also, because I am exceedingly lazy, the speech bubbles were made using a tool available here:

Robot:
------------
Measures about 3" tall.
Made using Lion Brand Cotton-Ease in Almond, althrough really, the color of yarn doesn't matter. The finished crocheted robot was covered in layer of gesso, then spray painted with silver metallic paint, and given a wash of darker pigment to bring out the texture. Washers and screws were added once the paint was dried. (The screws can be screwed directly into the finished item)

Effectively the same as the pattern available here:

Which is, in turn, based on a pattern available in my book, Creepy Cute Crochet.

Space Worm:

Measures about 4.75" across at the mouth and 22" long.
