I'm planning on making my own invitations, but I'm just getting started with the designing of them. I think I'm going to order the card pockets online, then get cardstock from a craft store to cut my own inserts. I've seen several posts on here about creating your own design then having the invitations printed at Kinkos or somewhere, but I'm not really sure what to use to create the design. What program would you recommend using? Are there any that are free or that offer a free trial period?
