This was my reply to your other thread:
It would depend on where and how you are going to sell them. If you are thinking of Etsy, research what like items sell for; ditto with eBay and wherever else you are thinking of. If it is local, you need to ask local people since prices vary all across the country.
Please know that the field is very crowded. And Prism99 is right. without the ability to buy wholesale you will find it hard to make any money at this.
Sorry - not trying to discourage you. But we all would be making money from sewing if we could. You may be able to hit on just the right unique and appealing "thing" that will be greatly sellable!
