I made this for my teacher!

Does it look okay? I made it as I'll post a Welcome back thing! As she was on leave to take care of her new baby and got married!

It should be Bienvenida since you are addressing a female.
Don't forget to pass on our congratualtions on the birth of her baby.
Okay, How about this?

It looks great. The words "de nuevo" are not needed.
Use bienvenida since your teacher is female. If the teacher were male then bienvenido is needed.
It didn't dawn on me that you might be trying to say "welcome back" when you wrote Bienvenida de nuevo (Welcome again).
If you were, then try: Bienvenida de vuelta.
oops I have to delete them!
Sorry I have to edit it better! I'll do what you said and also leave my name out as It had my last name in it! Sorry my Mistake!!! ![]()
I posted a new one! ![]()
Does it matter if de nuevo is in there? I can't take it out as I don't know the font as I made it a while ago and she only just came back! :(
