We're not particularly religious, and will be having a fairly simple/straightforward ceremony with traditional vows. My sister's ceremony was simple too, but it felt super rushed and awkward (it was like 5 minutes). We want to add readings to personalize it and add some length, but aren't sure how many would be too many. There are 3-4 that we like, none of which are very long (like they'll take about a minute each). Is that too much? I think I want the ceremony to last 15-20 minutes but as it is now, it'd be more like 10 or less.
