Button, Button, Who's Got the Button?

This weekend,

I made some polymer clay buttons. 

Although they are not ready to sell yet,

I'd like for your to see them.

They do need to be sanded and varnished and have a patina added.

I like these buttons, and I am thinking of adding a section in my Etsy store called

Buttons

so I can sell them.

Now, after looking at these buttons, 

and, 

remembering that they are not finished yet,

if you could help me by answering some questions,

I would appreciate it.

 

Question 1:  These buttons are between 3/4" and 1" across.

Should they be sold in set or should they be sold alone.

 

Question 2:  If sold in sets, should these buttons be sold as mixed sets

or the same button in each set?

 

Question 3:  How many buttons should I put in to a set?

Okay, here are the buttons.

When these are ready for sale, they will be fantastic!

So, can you help me with the marketing part of the buttons by answering the question?

I would appreciate it!!

Thanks.
