The Nursery: Alphabet Cards

Back in May, I went on an overnight girls trip into the city (Boston - I'm there all the time but this was different cause it was purely for fun and we stayed in a fancy hotel right on the Common) with a few of my friends. Of course this had to involve shopping on Newbury Street (I can only handle this for a few hours, but the other ladies I was with are die-hards...an ice cream break kept me going!) and entering every baby boutique we saw (one of the other girls is also pregnant with a girl due a week after me and the other 2 have young kids). While the other expectant mom bought all kinds of cute clothes for her little one, I bought BG some more room decor...a pack of Alphabet Cards by Cavallini from the shop Lester Harry's. Figures:)

So now I have to figure out how to hang all 26 of these suckers up! Here's some inspiration pics I found of some different ways to use alphabet cards in a nursery:

{mounted on artist canvas and secured with silver brads...check out the tutorial on the blog tiny Decor here}

{high around the room like a border...these are DIY cards by mom and dad Natalie and Keith for baby Roman...via oh dee doh}

{on vintage wallpaper and framed...from PaperNest's photostream}

{hung on some kind of line - these cards are a horizontal format just like mine...via Canadian House and Home}

Now, although I love the whimsy hanging these would add to the room, I still keep going back to a basic symmetrical grid right on the wall. Sort of like this:

I've always loved the idea of many small similar things being grouped together to create one large scale dramatic moment. I definitely want to use all the letters, but 26? That's not divisible by anything...except 2 and 13. Urggghhh. I guess we'll solve that problem when we get to it!

I could mount them all on something larger, like canvas with fabric, but this seems like more work and I'm already wondering how much of this room I'm going to get done before she gets here (the countdown is on - only 49 days until our due date!). So I think I'm looking for the easiest way possible to get all these things directly on the wall. Can you guys think of any adhesive or anything that I could use to stick these right to the wall that will hold them securely? Any and all suggestions for mounting are welcome:) Do any of you have alphabet cards somewhere in your home? Or just a collection of small art grouped together? Thanks!
