Hey ladies, new here! just my two cents!
I think its tacky to include the registry info on the invite, period. Put it on an insert in the envelope. I'll be doing something similar to this: a gender reveal shower, throwing my own. However, this is a no big gift shower. Sure, bring me bags of pretzel m&ms or gift cards, whatever, but i feel like gifts shouldn't be the point of a shower like this. I'm more focused on having fun with my guests and showing off my DIY deco skills (;
