Hi Amy
Here is one quick explanation how to create a Treasury , I found
this helpful guide from one of my other teamies.
Hope help you to create your first Treasury
1. Click orange etsy logo - top left corner to go to main page
2. Find treasury link - under "more ways to shop" bottom left of that page, click "treasury"
3. under "curator tools" top right of this new page, click "create a list"
A page will open up with blanks to fill - skip the description, title and tags (for now) and focus on the 16 blocks below.
Open a new search engine tab, leaving the treasury tab open Find an item (anywhere in etsy) that grabs your attention - I do this on a separate tab. Copy the url of that item and move back to the tab with the open blank treasury on it. Paste in into the blank that says "listing URL" and hit enter - the picture will show up in the block.
Now, using separate tabs find 15 more items that "match" your first item, based upon theme of the first AND color pallet. Try to stay within a color scheme and theme. Search until you find them. Reposition, by dragging photo blocks until you are happy with the visual flow from one item to the next.
NOW, fill in your title, the item description, and various tags that will apply to your treasury. This process is quicker (usually) when using all people from one team as you simply open a tab for each of 16 team members and pick something applicable. It becomes harder, when team members do not have a myriad of colors and decent photos to choose from. Try to never use blurry photos. They throw off everything Try to stick with a color scheme for visual flow. If you are beginning - start with neutrals, black and white, or all one color.
Remember to shift your photo flow by dragging your treasury photos around before posting - sometimes that's all it takes. Try to fill all 16 blocks for a chance to be featured by etsy on the front page.
