Yup, it's possible. I now have a design and basic layout for a program (as much as you can have without a ceremony plan, set bridal party, location etc) plus a plan for a little DIY decorative fastener for it that won't make me want to kill myself. Can't post pictures because it won't really make any sense, but I'm excited about it.
Also super excited about a pretty simple decorating idea that is very us. I love it and REALLY hope it'll work out. We'll see though - it's more DIY but I'm not worried about that. Shouldn't be too bad I don't think, but we'll see once we have a date to have to be within.
