Do you know what the time limit is on a wedding gift thank you note? Yes, there's a best before date on these things.
The famous Emily Post, now 'The Emily Post Institute' says the following:
When should notes be written?
Contrary to popular myth, the happy couple does not have a year’s grace period in which to write their notes. All thank-you notes should be written within three months of the receipt of the gift. Ideally, a response should be written on the day you receive a wedding gift. If that’s not possible, set a daily goal. It’s a lot easier to write three or four notes a day than to have to write a hundred notes in a month after the wedding!
