Hi Gillian, your work and photos are gorgeous!
You need to make a shop announcement starting out with what you are selling "Handmade curtains, drapes, window treatments. Welcome to ....."
You need to creat a profile telling something about you, your inspiration, your art, etc. Look at some other shops to get ideas.
WOW! first page on google, so manyviews, that is awesome for being sonew. Sometimes first sale takes months!! Keep at it, read all you can about tags, titles, descriptions; you must be doing something right for successful googling!
Good Luck :) :)
