Watch The Muppets T-Shirt Printing Process at Threadless I really love behind-the-scenes videos. This time around our good friends at Threadless show how Sharpint utilizes direct-to-garment printing to print the very fun Threadless x The Muppets T-Shirt. Sold? Thought so. You can pick up your favorite Threadless x The Muppets T-Shirts, priced between $20-$24, directly straight from Threadless.
