Assuming you are doing all you know;

1st go to blogs and ask what is wrong.

Rarely will you get a full answer but it is worth a try.

Then do a search of other products like yours.

If they are not selling either ; try dropping price ; if possible ; better to sell at a small loss to build a following than not sell and loose fees anyway.

GIVE GREAT FEEDBACK; NOT EASY BUT NECESSARY. yOU ARE MAKING FRIENDS.

Friends will buy a little when you keep in touch   , honestly , a thank you e- mail; ention new items ;ask their opinions.

Often this is something they want. Never know if they do not see it.

At times nothing asells.

This is the time to research new items.

What else do you and friends buy?

Sell that.

Go to pawn shops , people collect all sorts of unusual items.

Go on line ; see what the big stores are selling item for.

Check grocery  and drug store clearance sales.

Most of all; enjoy life. Selling is fun. it is not the only way to make money.

Paint ? Try selling some.

Any hobby may yield a following.

Try different things.

Check friends ideas and "wish" lists.

You will find something that s right for you.

Look in old repair shops; a lot of people buy unworking itemsto repair or canabalize.

Best of luck , we have all been there.
