Linda Mitchell is a freelance artist in California who has been designing toys for companies like Spinmasters for years. In her spare time, under the name Linda Panda, she has developed her own characters into a line of merchandise which includes enamel pins and patches.
Her Doe eyed cartoonish characters remind me of the "Kawaii" designs of Japan and will be sure to bring a smile to your face. My personal favorite are her snack themed "too cute to eat" line of lapel pins with plays on names like "Catpuccino" and Puptarts. The pins are very high quality with rubber clutches and the artful backings are worthy of collecting themselves.
These items and more can be purchased through her Etsy store here.
