I like to make customized cards for weddings that I attend. Not only does it save money but I think that it's a small way to make an impersonal gift (like a gift card) a bit more personal. Plus, it's always fun to find a quote that works for the couple and to try to determine wedding colors to use from the invitation.
I even made one of these for my husband and I (upper right) for the day we started dating (cute—I know!) and plan to hang it in our home somewhere when I find the time :)
I'm looking forward to making more of these for our upcoming summer weddings!
