scannable QR code can be done in single crochet or double crochet! perfect for hanging in your store or studio, taking to pop-ups as an interactive experience for customers, or even attaching to a jacket or tote bag to make yourself a walking advertisement!

MATERIALS ♡

2 dowel rods in finished width if not sewing finished piece onto something
scissors, tapestry needle
3mm hook + size 3 lightweight yarn

GAUGE ♡

3mm hook + size 3 lightweight yarn

9 rows of 9 single crochet = 2” x 2”
7 rows of 13 double crochet = 3” x 3”

the QR code I got was 33 pixels by 33 pixels so any variance in that may alter your finished size
both of these are made with a 3mm hook & size 3 yarn
the one on the tote bag is done with single crochet and measures 7” by 7” (about 18cm) this size is better for attaching to something flexible as it will be easier to keep straight for scanning
the one on the wall is done with double crochet and measures 15” by 15” (about 38cm) this one looks cleaner and is easier to see & scan from a distance

GET QR CODE ♡

be sure to use a “static” code rather than a “dynamic” code

be sure that it leads to the right destination

be sure you are using a code that will not expire or require a subscription to keep active

GRAPH OUT QR CODE ♡

I recommend graphing out the QR code pixels so you can mark off your rows as you go & not get confused

I used stitch fiddle, here is my example code

CROCHET QR CODE ♡

for the smaller size: start with a chain in the number of pixels you have, chain 1 turning chain every row (does not count as a stitch) work 1 row of 1 single crochet for every pixel

for the larger size: start with a chain twice the number of pixels you have, chain 2 turning chain every row (does not count as a stitch) work 1 row of 2 double crochets for every pixel

when finished, scan from a slight distance! ♡

for best results, wet block your finished work; double check that it scans when it is positioned for blocking

ATTACHING TO RODS ♡

after you’ve finished your work, you can pull up a loop and single crochet every stitch across the top to a dowel rod; do the same along the bottom

ATTACHING TO FABRIC ♡

if you prefer to attach the QR code to a jacket or tote bag, pin it in place and check again that it scans when pinned; hand sew or machine sew with a straight stitch near the edge of the crochet
