okay.. and i will still create new customisations. How should i ensure that it is saved in a separate template file. will word give me such option while saving..?

All you need do is have a document based on the template open, so that any new customizations can be added to that document's template. You get this option when you're creating the customizations, not when saving the file.

The case is.. I deleted the normal.dotm file. Then I opened a new word document and saved it as a .dotm file with a new name. This file did not have the old customizations that I had done previously. The problem is when I again create a new macro, it is once again stored in the normal.dotm file. In VBE it shows the normal template as well as the template which I created. I can copy the macros in my new template. But, isn't there a way to directly make the macros be stored in my new template.

If there is no way for this, and copying is the only alternative should I insert a new module to copy the macros...?

As I said previously, to create macros and have them stored in the new template, you'd need to first create a new document based on that template. If you create a document based on the normal template, that's the only template Word will off for you to store them in. You could also open the template for editing and do all the creation in it directly.
Well, you could certainly do that, but it really isn't necessary if you do the creation using the proper template in the first place.

Okay, I understand.
Please tell how should I create a new document using a new template. This is what I have currently--

The original normal.dotm i.e. with no customizations or modifications.

Now further whatever macros I create, i want them to be in a different template. So what should be my first step? If i open a new file and save it as some .dotm file with new name, it will have the normal.dotm associated with it..

I don't get the exact procedure.. Please, Kindly help..
