Hello and welcome to Zealot. You have come to the right place for ALL THINGS SCI-FI. We have many members who are into SCI-FI (myself included). So I hope that you will feel at home here.
The white glue should not bother your wife at all. I would also suggest getting water colour paints for painting the edges.
If you have any photos of any of the models that you have built, by all means, please post them (WE LOVE SEEING PHOTOS!

)
With the paper models that you have now, if you can, please post a build thread. Build threads are a great way of showing off your skills and talents, as well as highlighting problem areas that you may need help with.
If you have any questions, comments, concerns, need help or advice, please feel free to ask and we will do what we can to help you (or at least point you in the right direction).
Once again, welcome aboard. I hope that you enjoy yourself here. I am looking forward to seeing your work!!!
