I finally did it. I've had so many Etsy friends create treasuries, but I had never tried it. Finally, after some encouragement I finally tried it. I created my list in poster sketch: http://www.etsy.com/poster_sketch.php, I then waited until it was time for the list to open up.
I don't even know what I did, but next thing I know it was asking me for a title. I typed that in quickly, thinking I don't have much time. I then was faced with a blank page, with just my title and name. Now what was I to do? I didn't want to click on anything and loose my opportunity. I finally noticed the little spaces for me to type in the listing numbers. It took me a few to learn that on my poster sketch, if I click on the edit button under each item, it will give me the item number and I can copy and paste. Wow, now that was easy!
So, after an adrenline rush, the excitement is over. I guess I have to create another one now!
