Is it rude to ask for wedding monetary gifts? We already have a blender (and pretty much everything else!).
Well, you should never ask for specific gifts, monetary or otherwise. What you can do is let them know (if they ask) that you would prefer cash gifts. Let your parents, siblings, wedding party, and close friends know too -- and if guests ask them, have them relay your preference. But don't announce it in a formal way to your guests (whatever you do, don't mention it on the invitation!). If guests are curious, they'll ask someone close to you what you would types of gifts your would like to receive. Still, some guests will want to buy you material gifts -- so it's a good idea to register somewhere for a few items. And of course, be sure to accept and acknowledge every gift gracefully (that means send out thank-you notes). As for monetary gifts, let the giver know how you intend to spend their gift in a thank-you card.
