So, long ago in a galaxy not-so-far-away, friends of ours did a cash registry for their home improvement projects. They were renovating an old home, so they found a registry that had a 3D house and people could click on the things they wanted to donate towards. I'm trying to find that registry again, but I can't seem to find it anywhere. We've asked the friends who used it, and they can't seem to remember (it's been quite some time.)
Now, I don't have time for people to tell me I'm being tacky. It's in our culture for our families to give money at weddings. We are just offering another option for them so they don't have to bring cash.
