I have written a MET/CAL procedure that takes up to 10 points and does a 3rd order polynomial curve fit. We use it to make extrapolated tables for flowmeters and some force transducers.
The prodcedure provides the same results as you would get from: PFitData(B2:B12,A2:A12,3) OR from the Linest equivalent: LINEST(A2:A12,B2:B12^{1,2,3},1,1). If you are interested let me know - michthai@yahoo.com.

If you are creative, another option you can choose is to create your own wedding invitation wording . When you start from scratch on your own, you can literally design every single aspect of your winter wedding invitations . One idea if you create yourown wedding invitations are to use pre-designed paper or paper that already has a pattern, and the rest of the invitation can be created on your own. Another idea is to use special add-ons instead of having flat paper cheap wedding invitations. Special add-ons allow you to emphasize the unique nature of your cheap wedding invitations. For instance, you can have a vellum sheet over the actual invitation, giving a glazed look and held in place by a winter-designed ribbon.
