If the customer can only have one paper, then that is quite easy - all you have to do is create a field in the Customer table which is athe same datatype as the ID for the Paper table rows, and put the ID for teh paper into the customer table.
So, if you have a Paper table
ID (int) PaperName (varchar(200))
1 Times
2 Mirror
3 Globe
And a Customer table
ID (int) CustomerName (varchar(200)) PaperID (int)
1 Joe 2
2 Mike 3
3 Dave 2
Then that would indicate that Joe and Dave both take the "Mirror" paper, while Mike takes the "Globe". (You can also set the PaperID as a Foreign Key, and SQL will enforce that ID match)
If you want a customer to be able to take both the Mirror and the Globe, then you need to set up a third table instead which has the CustomerID and the PaperID:
ID (int) PaperName (varchar(200))
1 Times
2 Mirror
3 Globe
ID (int) CustomerName (varchar(200))
1 Joe
2 Mike
3 Dave
ID (int) CustID (int) PaperID (int)
1 1 2
2 2 3
3 3 2
4 3 3
