I can understand exactly, it would be hard not having anykind of theme since that gives you so much to decide from and with all the stamp stuff deciding can drive you crazy
. I just recently did my first swap ever, course the theme was wheels, I figured I wanted something simple, but sweet. I didn't want to over-do-it, but I didn't want to under-do-it either. I just went with the flow. I hope to get better at stuff as time passes though and to maybe do another swap down the road. The card I made for my first and only swap so far is below:

Best of luck to you, I know whatever you come up will be fine
