Anand Duncan contacted me earlier this year about making little plushie versions of her Gamma Girls characters, Beta and Pi. Check out the Gamma Girls animated adventures in space at TeamGammaGirls.com
Anand had a pretty clear version of the type of simple, fun plush toys that she wanted me to make, which always helps. The faces are taken directly from Anand's illustrations, she drew the specific expressions she wanted and I just turned those into machine embroidery files. I mostly used fleece and craft velour to make them, with some little pieces of other fabrics to match the colors that Anand already had used to design her characters.
The toys are about 8 inches tall. Even though their shapes are simple, there are actually a lot of pieces layered to create all the different shapes for their outfits.
