if you're going to use ms word as an image manipulator, you're going to have a bad time
tbh I haven't used word in god knows how long, even in college I used photoshop for papers to fuck with the kerning for length and occasionally rastorize the text so it slopes down near the end of the page to mess with the professors(makes you read the same sentence you started at, pretty frustrating)
if you pm me with more info I might be able to help you out, being your wedding and all it sounds somewhat serious
