Need ideas for a present

[kel1234]

So I'm looking for advice on a wedding present I can get for two friends of ours (well really she was more a friend of my husband, but now I'd consider them family friends).
It needs to be something that can be posted, as unfortunately we are unable to go despite many people on here telling we we were unreasonable for this, we have tried to work out a way it could work and we could go, but it just isn't possible (the wedding is a long way from where we live, and would mean a train, a plane, another train, then a bus or a ferry, then the same back. We don't drive, so transport at the wedding would also be an issue. Finally we were not comfortable leaving our little boy and going so far away). Anyway we explained all this to them and they completely understood.
Anyway the other thing is that the bride doesn't really want all the big wedding at all, she's more doing it for family reasons. I have seen some lovely personalised things we could get, but the basic idea is that they all say "Mr & Mrs ...", and we don't know if she will be taking his last name.
Any ideas as to what we can get them? (We don't know the colour scheme either which doesn't help).
Thanks
