Design a faux/false set of 5 postage "stamps" with the theme of Christmas

Information for the business: Positively Postal sells stamps/postal products
Industry: Art and Design
Design details: I am looking for a design for a faux/false set of 5 postage "stamps" which I will have printed and use to sell on the Positively Postal blog as well as promote it. The theme of these stamps is Christmas. I would like the words Positively Postal to be incorporated as well as denominations/values (each one = 70p) with small envelope symbol - see the url for those details. Stamps do not have to be the same size as those shown under this url but they should ideally be square or rectangular. The values/envelopes on previous stamps have been too small so I would like the 70p plus envelope symbol for these to be bigger/clearer. Possible items/themes to include = doves delivering letters but open to other suggestions. Final designs need to be in high resolution for printing.
Ideas for the visual style: Elelgant, peaceful, classical
Urls to draw inspiration from: http://positivelypostal.com/positively-postals-fabulous-arti-stamps/
Where the design will be used: Print & Web
