Was at 7 weddings in last 4 yrs, though one this yr early summer was an extended family do so it was a family group present that the mam organised.
The rest:
Wedding 1, mid 06 got a thank you card, though it was an afters, I bought something small
Wedding 2, mid 07, not sure got a card, though it was an afters but two of us clubbed into buying something. I know the groom better in this case.
Wedding 3 late 07 and got a thank you card.
Wedding 4, this time 2 yrs ago and got a thank you card.
Wedding 5, nearly this time a year ago and *no* thank you card.
Wedding 6, a month ago, no thank you card yet.
Most would know each other socially or at least to see.
Don't get on with no 4 anymore. 4, 5 and 6 know each other and 5 was a delibrate lack of manners due to the falling out of no 4 and a couple of other things, as she's into her etiqutte ala "Mrs Bouquet" or so she thinks. And she has handgiven others a card in my presence, the day I gave present (the wedding was abroad so within 2 weeks I had present with me when next meeting, wasn't the only one either but they opened 2 or 3 sets of presents in front of everyone - so not the done thing) so it was a snub.
I've more manners in my little finger.
I've moved on as they say. I get on with 3 and see her the most.
2-6 weeks is the norm, not a year.

"wedding gifts within two weeks after returning from the honeymoon.
Wedding gifts arriving in advance of the wedding, should be responded to immediately, so that an extended period of time does not pass between receiving the gift and it's thank you."

"The current guidelines for wedding gift thank you notes are that the notes should be sent within three months of receipt of gifts. However, given the potential monumental task that would pose to the bride and groom after their honeymoon, it makes sense to send notes out as soon as gifts are received (often wedding gifts are sent prior to the wedding date)."

"While it’s acceptable to send it up to three months after the big day, it’s best to do it within two weeks of returning from your honeymoon. After that, people will start wondering if you didn’t like their gifts."
My mam gets always upset about these things especially on some of the cousin's and their kids on presents - especially when they were young. I get her point too. It doesn't take much for a card or even a thank you phone call if a card is too much for some people to spend. I call them miserly, lazy, full of their own importance and shallow.
I've learned to weed those who don't out of my life..
