Treasuries are hand picked selections of items listed on Etsy and made by Etsy users. The treasury list is limited, in constant movement and each one only lasts for two or three days. It’s these collections that are usually chosen for the front page, so being featured in treasury lists increases the possibilities of appearing on the Etsy front page, and this means lots of visits. It’s not that easy to get a list though!
Go and have a look!
