My partner and I recently got some fancy new phones and one of the applications on there was to use a barcode scanner to read QR-codes. He showed me how by just filling in a little web form you can create this code and you can embed any kind of information in it in pretty much any language on earth. I jokingly said, "man that would be perfect for cross stitch." At which point the gauntlet was thrown and I had to do it. So what follows are the instructions on how to cross stitch your own business card patch for your coat.
Step 1: Supplies
What you'll need to do this are:
* An internet accessible computer
* An image manipulation program (GIMP is what I use here)
* 6 inches of Cross Stitch Canvas
* an embroidery hoop
* 1 skein of black embroidery thread
* an embroidery needle
* Heavy duty fusible interfacing
* An iron
* An ironing board
* White cotton thread
* (optional but highly recommended) sewing machine
* A red or orange marker (any color will do, but these show up best and allow you to see what you're doing)
* A rugged piece of clothing like a sweat jacket or coat
Step 2: Making the code
A quick Google search for a QR code generator will yield a good chunk of results. There are a couple good ones for making a business card. In this illustration I use the example code from the ZXing website. Super simple, just fill out the form, push the button and bam, you've got your code. Next is the hard part.
Step 3: Scaling the image
Using GIMP (the Gnu Image Manipulation Program, free software, free to download), open your image. If you have Photoshop, I have no idea how to help you.
Resize the image to 500 pixels. This will make things uniformly sized. To do this use the menu bar at the top go to Image > Scale Image and you'll get the dialogue box. Change both height and width to 500 pixels. To finish click "Scale."
