"Kits" to give the homeless

So I've decided that starting this summer I want to make small kits and have them available to donate to homeless people I see sometimes.  On my way to or from work, I sometimes see people standing on the corner with little cardboard signs.  I just feel as though this will be a good way for me to give more back.

I've been looking up ideas on Google, but if you have any ideas-especially for any little "luxuries" that might be nice to include.  I have the basics down, but I would like to include a little extra comfort items in the bags/kits.

I would love suggestions!  Thanks!
