I love the selection of some of the online sites like Zazzle. They are very unique, but if you are on a budget, I think it's a bit pricey. However, if you sign up with them, many times they will send offers and discount codes.
Recently my brother and his soon to be wife made some postcards for their wedding at Vistaprint.com. She used them in the past for work and got a really good deal on them. I believe the shipping was the biggest cost.
They looked very nice and professional and was personalized. My sister made her own. It wasn’t very inexpensive.
She got some with a picture already on them, so she just added the font in a black ink. Of course, if you go with the colored ink, it will run into some money. Those are really the only ones I have seen personally, but an interest search did product this that might be of some help.
postcards.com/save_the_date_postcards.html Some are just okay, while some were even kind of ugly, but many are really pretty and/or cute. Just like Zazzle, you can actually place their picture on the postcards. So that is a more personal touch.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
