::For those of you who don't know, an alphabet box or sound pouch* is simply a tool used to teach children sound recognition by using pictures and/or objects. There's a container for each letter and inside each container are about 6 (give or take a few) objects, each beginning with the sound of that letter.::
I've decided to split my answers to your questions into two posts. I tried writing everything in just one post and it was just way too long. So, first, I'll share
what's in our box - yes, that means there are
lots of pictures for you to look through. :) I'll also give you some
ideas and resources for where you can find your own teeny tiny goodies and
how you can create your own alphabet box. Finally, in Part II, I'll explain
how we use our box for learning and I'll have a little
giveaway (click here for the giveaway!), as well!

Next I'll share some tips, resources and ideas on how to make your own alphabet box.
First, the sounds:Before you begin searching for fun little objects, I recommend you read the little chart I've created below so you know the proper phonetic sound pronunciations for each letter. You may have the cutest little orange for your O drawer, but it won't work because the phonetic sound for O is quite different.

Second, the box: 
I found ours in the tool section of our version of a Lowes. It's one of those multi-compartment units used for storing nuts and bolts and the like, which you can find at almost any hardware store. Sadly, gray was the only color option I had. I tried to jazz it up with letter stickers from my scrapbooking stash. :)
*You don't need to limit yourself to a box - if you're crafty and willing to devote some time, why not make individual sound pouches, one for each letter?
Jojoebi did an amazing job at this - check out her photo stream
here. It's my hope to eventually transfer out of the box and into some homemade pouches. They look so much nicer!
Third, the contents:
You'll want to create small letter cards for each drawer. I think it's important to create a card for both capital and lowercase. Here are some options:
