I like your items, and the prices are good IMO. It irritates me when people underprice (though I've been told I'm guilty of it myself). I've been sewing for 13 years, so I know all the time and talent that goes into your sewn items!
I think you could add more to the announcements section at the top. Maybe about your expertise, why your items are special, etc. There are some run-on sentences in your policies section, and use of "are" instead of "our." That's the future English teacher in me :)
