I need a Hankie

So I've been thinking a lot about my invitation suites/Save The Dates, and I purchased a Cricut and a Yudu screenprinter in order to construct them.  Originally, I thought I had it all covered...my STD would have the date coming out of the side a la this:

Cute, huh?  And for my invitations, I bought chipboard and was going to bind it together as a book, with the cover covered in fabric.  Lofty idea, I know...but I think it's cute.  Here's a sneak peak at the idea for the first page:

I had to black out our identifying information so it looks weird.  I still need to work with color and stuff but I think it's getting close to a cute finished product.  Since I'm too cheap to buy Photoshop, I have to use GIMP which is great freeware, but not as user friendly.  I'll show you more details once Ive actually assembled one, but the idea is to actually have a book as the invite suite with a tear off RSVP postcard.

However, I also really want to incorporate vintage handkerchiefs.  Like this:

*swoon*  I'm in love!  But, now the question is, how do I incorporate these gorgeous hankies?!  I have a few ideas:
1.)Screen print my invite on them, add a little pocket into my invite book and place it in there.  This is not a bad idea, but kind of ruins my idea for having an invitation suite that will all stay together.
2.) Add them into my save the date card.  I think this would turn into overkill, and if I scrap the 3D date idea, then I would have bought a Cricut in vain :(.
3.) Screen print the menus on them and place them at everyone's seat.  They could serve as napkins (though this may be a bad idea, maybe they wouldn't be thick enough).  I could tie them with pretty twine, though.

Personally, #3 is my favorite option.  I'm just afraid they would look silly if they only served the purpose to have the menu printed on them and that they wouldn't be sturdy enough to actually work as a napkin. 

What do you guys think?  Should I just scrap my STD idea completely and use the hankies, add the pocket to my invites, or can I get away with my napkin idea?  Or do you have another idea entirely?  I'm a bit lost :(.  What have you done to make your invitations unique?
