Hi all- I thought we really rocked our registry and registered for like tons of stuff, but we just got back from our two showers and the registeries are more than half gone (75 people at the 2 showers combined, but there will be 300 at the wedding, so 150 "gift givers"). Is it rude if I don't add anything else to the registry and just hope people give us gift cards (and cash? My friends and family are WAY too generous and I just want to make thing easy on them--- what do you think??? thanks!
