Etsy is an online marketplace for handmade and vintage items, as well as craft supplies. It was founded in 2005 and has since become a popular destination for crafters and artisans to sell their products. Etsy provides a platform for sellers to create their own shops and list their items for sale. Buyers can browse through the selection of products and purchase items directly from the seller. Etsy is a great way for crafters to reach a wider audience and make money from their creations.
