Hi Martha,
You have lovely items! I have thought about opening a new shop for my bath and body items ( I am working on making enough items to sell on etsy before i make my final decision) My advice to you ( and a bit of a warning) is that two shops equal twice the work. My suggestion would be to make a few of the items that you have in mind and make a new section on your shop and if the items sell quite well than you could think about opening a new shop. I wouldn't open a new shop until you have at least sold 3 or 4 of the items you are planning on making - Just to be safe. I plan on selling a few of the items i have in mind to make on etsy, wait and see how well they do in sales before I jump into making a new shop, that way I know if they don't sell very well I can just deleted the items and give them a way as gifts to friends and family.
I think your ideas in mind are great ideas and I hope they sell like hot cakes. But I wouldn't jump into making another shop until you have people interested in your items.
hope this helps,
- Devon
