It is the season to be jolly, so I bought Christmas cards from charity shops to send to my penpals around the world. For the greeting, I like the wording similar to either Merry Christmas and Happy New Year, or, Season's Greetings. However, many just have Christmas greetings so that means writing in Happy New Year.
Now, the weight of the cards can be an issue, with some really fancy ones over 20g. This then falls into the 20-100g postage band. No good. So, limited to smaller cards. I bought square cards, some bigger than others. The smaller ones are a good weight and even allow room for a sheet or two of paper for a letter. So, I write my letters and enclose them with a smallish square Christmas card. I post it, having looked up at the pricing leaflet from Royal Mail I picked up in May, with correct postage. I head over to Twitter but am dismayed when one post office tweeted about a minimum size for international mail. I responded to Royal Mail wondering if my slightly shy of a minimum 14cm on one dimension on the envelopes (supplied with the cards) would still get to Germany and USA. The reply is yes, as long as enough postage has been used but also to check https://personal.help.royalmail.com/app/answers/detail/a_id/121 - this shows indeed a minimum size.

In the US, there may be a surcharge on square letters as the one dimension falls into non-machineable thingywhatsit (maybe a "which way is up" problem for the machines). I was wondering then whether Royal Mail will head down that route in the future and add a surcharge.
So, I have a bunch of under 140mm square Christmas cards to get through. There is no reported minimum size for domestic mail. So, I can use for them.
What a jolly scene. I have sneaked a few of the into 7 inch by 5 inch envelopes and this is under the 20g.
I bought also smaller cards to fit into the C6 (roughly 6 inch by 4 inch) envelopes. However, these ones I have to write in the New Year greeting. This size or even lightweight cards to fit into the C6 envelopes are rare.
So, I thought, if I have to write in Happy New Year, why not go for blank cards. I came across some nice folded gift tags and thought - they'd do for festive cards. I can then place more emphasis on the letter... size doesn't matter (it is the thought that counts?) and I can write my own greeting.
