I think you are doing very well in sales for your first month and that's the bottom line. One thing I would suggest is in your titles. Start with what it is. Normally a person would not use "beautiful" in a search for an item so don't start your listing with that word. They would search for Girls skirt or Girls tutu so you could start with either or Girls tutu skirt. Then give the size and/or age and, type of fabric and color. If you have made it put Handmade in the title. Also New. See if you can get all those things into the Google preview window below.
If they all fit then put descriptive words like Beautiful Ballet Costume or whatever. Or if you think people might be doing a search for ballet costumes then you could start out with Girls Tutu Ballet Costume, then size, fabric, color, etc.
The words don't have to make sense, they just have to be search words. It's more important to have a lot of key words in the title than in the tags because I have seen listings fail to show up in a search using a word that was in the tags but not in the title.
When you have made a new items post it in the new listing thread in all your teams. Craftori team is for handmade.
You can learn a lot by going other people's stores who sell the same type of items you do. Look at the titles, texts and tags of those who are successful and compare them with those who aren't doing as well. You can see the tags in other people's items by clicking on Show Item Details at the bottom of the listing.
Treasuries: Pick something you love, be sure to use all your tags, send everyone a convo who you have featured, post your treasury in all your teams and send a link to anyone who might be interested. Use all the spaces, don't leave any empty and when items disappear (they will if they expire) fill them with new items and send a convo to the new person featured.
I would be a little more flexible in my policies because your customer is your friend not your adversary, but that's just me. Good luck.
