So cute and fun!! Love the pictures - the clothespins are a great idea!
One thing that I noticed in your policies was this: All international buyers are responsible for customs
What does this mean? You definitely want to expand on this. As a seller, I have to ship often internationally, and I always fill out the customs form for the sellers. Are you saying that they need to fill it out first and then send it to you? Or does customs mean something different? Buyers may not know this, and personally, if I were an international buyer, this would turn me off.
Also, for your prints, it would be fun to see them framed, hanging on a wall, or in use somewhere, to get an idea of how to use it.
As for tags, I always think "what would someone search if they wanted to find my product?" So don't make tags too complicated. Use something generic, like "clown print" or "black and white print".
Hope this helps! Such a fun, unique store!!
