Step 1:
Take a pair of Converse, preferably from your closet - I cheated and bought a pair from Urban Outfitters that were pre-frayed. I know, I know, sorta lame but it saved me a step and I didn't have any old pairs left.

Step 2:
If they aren't thrashed enough, distress them with a nip here and there - maybe a little sandpaper, etc.

Step 3:
Use a sharp needle and get to embroidering. I suggest not over-decorating as tempting as this may be because too cute just ain't that cute.
('Trust' has been my word/mantra for a long, long time. I used 'Me...' as a little joke on the other shoe where it rests just below my tattoo. I'm all about the subtle double entendre... see this post to further illuminate.)

Step 4:
Shoes too white like mine were? Remove laces, put both shoes and the separated laces in a big bowl and soak them in black tea to desired agedness. I used cold tea and let them soak overnight. I imagine hot tea would get the job done faster.

Et Voila! Your very own, completely individualized, revived and spunky tennies :)
