I know lots of people use this site, I have zero experience on it. Any and all tips are helpful at this point.I'm looking for the following:1. small basic cards to print directions on2. the photo sharing card telling people where to upload pics they took (and what size of these things should I be looking at?)Now, obv. the directions cards go in the invitation envelopes, what about the picture card? Also in there or do guests get those at the reception?As the title of the post reads...I'm clueless.TIA.
