I ended up finding two boxes of invitations on clearance at Target. They are technically wedding invitations, but oh well. I'm on a budget, they are merely elegant and have purple flowers on the overlay part of the invitation - a solid representation of my personality. For less than $20 for invitations and thank you cards for 50, was well worth it. And they are ones you can print on. So at the top you can clearly see it is a baby shower to celebrate the upcoming birth of my daughter - and it lists her name.
I'm not hosting my shower, just helping my mom put things together. Its just something she and I are bonding over. :)
