kalyani,
Great work and it is most required art ..earnings are also good as lot of hardwork needed..
There are many ways to promote your product...Other than Ebay, rediff, Amazon and popular b2b sites...you can create your own blog to promote it .
Create a account in Ebay or other sites which have facility to sell items..
I hope you can create a blog with the pictures of your work and some good content to describe it so that buying or people interested in embroidery work can get an idea on your work.
Put this link in ebay while advertising your product...
I am suggesting online selling sites for easy payment but if you have any other way for payment like cheque or DD you can directly advertise your blog link in social networking sites and facebook too.
Facebook have advertising space where you can put free ads of your product which can be viewable to audience around the world..
Hope this helps you
Regards
