I make listing items on etsy easier by writing the text previous to listing, with its title on top. I have a simple program called TextEdit, you all proly have something similar on your PCs that is just the simplest thing for writing up notes with minimal frills?
OK, once you have that text ready and your photos all edited and good to go, find the item in your shop that is most similar to the one you're listing and click it. On top you'll see a blue bar with several options. Click 'Copy.' You can also do this with sold items.
Now you will be in the 'list item' page of that item- but it won't be that item! That item is still safe in your shop. Now remove all the pictures and upload the pictures of your new item you're listing. Remember, etsy gives you 5 chances, use them all. Show the backs of your items, show a size comparison, let the person really know what they're getting. Also, the 1st picture has to be your 'eye-catcher.' This might be a portion of the item, it might be the item in a rumpled pile- it just has to be your prettiest picture.
Anyways, then click Preview and then Publish. Das it!
By the way, if you make beads and sales are slow, try splitting your beads into smaller lots. Remember people are cheap! buying a whole strand for $20 is a big commitment! Also, the reason people always need to destash is from having to buy whole strands of beads but only having plans for, say, 3 of them. So try selling in batches of 3. You don't need to change your pictures or description, just add '3PCS' to the title and in the description, include "You will receive three (3) pieces."
