I am in the 60's group and personally I would love it if any of the multitiude of my nieces, nieces in law, nephews, great- nieces etc made me a quilt. Or even my daughter or son! (They all love the quilts I make them!) I would use any quilt proudly.
My point is you should do what your heart says. It is a lovely quilt. She will love it if she loves you! If you feel better doing another one, that's great too. I never though try to make a quilt for someones's bedroom decor. People change too much!
Oh and for your border question: every time someone adds a border to "make the quilt bigger" the end result looks like the border was an afterthought and was added to make the quilt bigger. My opinion. This quilt does not need a border. It looks complete without one.
