Wedding monograms

One of my technicians at work is getting married in September and because I love doing crafty things and I'm trying to figure out this whole photoshop thing I told her I'd try and make her some little monograms to put on goodie bags, menus, etc. So here are some of the things I've come up with so far. I can't get my version of photoshop to "rasterize". If anyone knows what this means and what I'm doing wrong please let me know :)
