A "Loonakit" is a ball-shaped bit of adorableness. I've been sewing them for years, and have adapted the ball pattern to all kinds of different creatures, including ponies!
if you'd like the chance to get a pony Loonakit of your very own, check out my kickstater campaign, https://www.kickstarter.com/projects/1285575774/embroidered-equines-20-cooler-pony-plushes (It's almost funded! At the current average pledge, I need just three more backers to reach the goal! Yay!)
