Your mission, if you choose to accept, is to focus on the customer's needs and show them buying from you is getting them something more than buying somewhere else. To do this you need to be able to tell and show them why your product stands out.
Step one is obviously to have a product that does offer a little more. Your items don't have to be completely unique but there should be something beyond I put love into this or it is one of a kind. My daughter's hand print ash tray she made in kindergarten was made with love and is one of a kind but no one really cares but me. Figure out what that is, if you can't, why should your customer?
1. Tell customer why what you are selling is different and why what they get has value.
The basic idea. is to tell customers what is there and they should care. You use expensive hand picked jewelry, woopee, tell them why. Are you picking the most lustrous beads, special designs, what does your work bring to them.
Your make-up is organic- what does than mean for me? Does it last longer, what are the colors like, bring up ingredients if they make a difference to the actual make-up. Sensitive skin can be a factor but it often for many people it is not a deciding factor.
Basically assume customers know nothing about your item and process, often they don't, and explain what it is about your item that makes it stand out and why.
2. Are you actually adding value where it counts?
This can be a harsh one but take a hard look, which features actually add value. I'm suggesting making something shoddy but rather that if you are spending more for something doesn't affect the customer, you might want to rethink it. Put the effort and time into what counts.
Maybe even rethink your product. I saw beautiful hand painted yoga bags but at 75 dollars for a bag, that was way out my range, I don't want to spend that much on a leather bag, never mind canvas. Someone suggested why not try selling the painted canvas as wall hangings. That bring me to my next point
3. Figure out your market and what they want
I talked about finding your target audience but once you do, take a look at what they are looking for. Just start with price range, does it make sense? There are items at all level but take a look at where similar are priced. If most canvas tote bags top out at about 40 max, you're going to have a tough job with a single purpose bag that is almost double that price. Will making it a different style-say more traditional shape bag draw in more people, can you do anything to lower the price?
4. Great pictures that really show the item.
Magazine shots and fancy angles are great especially to draw people in but since they can't pick it, have some good crisp shots of all sides so customers have a real idea of what they will be getting. No matter how good you describe it, if they can't see it, they are not going to buy.
5. Last but definitely not least, make them want it.
Use their emotions to grab them. Will it make them feel good. How will they feel wearing this piece of jewelry. Is it cosy, does it make a statement? Pick one and work with that.
My point in all of these is when you write your descriptions, you have to focus on the customer and what they want. Tell them what they need this item for and how this fulfills that need.
