M.L.
I'm a seller there as well as a buyer and think that it is a wonderful idea to support handmade items.
Sometimes, searches can be a little difficult, but many people do custom request and monogramming.
You can place a special request in which people bid on your item here:

or you can search for items here:

narrow down the search by adding in color or style you would like.
