Your treasuries are beautiful! Do you contact every person that you have included with a link to the treasury? Include a nice note encouraging them to take a peek, comment, favorite, tweet, share on Facebook, etc.
Also, join several teams and enter their treasury challenges. There are also teams just for creating treasuries.
If you want to attract the attention of the Etsy staff, make sure that most of your items have white backgrounds and include a mixture of handmade and vintage. Also, it helps to have a wide variety of items.
Keep up the nice work and good luck!
