Roadhomequilting; when I do my listing I have 4 tabs open. One to ETSY for my new listing, one to Wiki patterns to search/copy/paste info; one to Cemetarian for dating info; and one to google to look for other prices for the same pattern. I copy/paste the info from Wiki and it makes the listing go so much faster. If I have something that is not on the Wiki, I add and upload it on "off" time so that when I am ready to list the info is already typed up. I think the moment of listing is important and should be as complete as you can possibly manage. You can, of course, tweak later, but you want to look professional and give all the info you can in your initial posting.
