Welcome from Kentucky. All of the above is good advice. One of my first quilt projects was a memory quilt for my parents' 80th birthdays. That was only 7 years ago but when I think about it, I could do so much better now. The important thing is that they loved it and I'm sure your nephew will too. Like everybody said, there are lots of sites on the web to give you ideas and there are several books out there with how-tos and ideas also (I'm mid-50s, too so I'm more comfortable with a book in front of me than a computer!). You might be able to find some at the library so you don't have to go out and buy a bunch (quilting is big here and my local libraries have a ton of books but I know others say they can't find any at theirs).
Good luck and feel free to ask if you need any guidance.
