What happens when you combine the warm and fuzzy art of knitting and crochet with the gritty urban landscape? A phenomenon known as knitfiti, or yarn bombing!
Whether it’s wrapping a bike rack in colorful wool, knitting a cozy for a stop sign or covering a tree trunk in crochet, yarn bombing brings warmth and whimsy to things that have neither. In other words: it makes people smile.
If you’ve ever had a yearning to make the world a more cuddly place, then you’re in luck. We’ve got everything you need to know to take your handicraft off the couch and into the streets. Bombs away!
What is Yarn Bombing, Exactly?
A yarn bomb is a form of street art where yarn in any form (knit, crochet, latch hook, cross stitch, amigurumi or simple wrapping) adorns an object in the public environment. Think of it as graffiti, just sweeter and kinder (yarn installations aren’t permanent or destructive).
How to Yarn Bomb
1. Find the Target
Look around for a simple, plain object that might benefit from a little softness and color. Ideally, it should be close to home (so you won’t have to travel far and can keep an eye on it). It’s also a good idea to check in with the art council or city council if it’s on public property.
If you plan to knit or crochet a fabric, then choose a 3D object that you can sew your fabric around, like a tree, street post or statue. While scoping out your options, make sure there’s a way to keep your yarn bomb from falling down. If you choose to wrap a street-sign pole, for example, you’ll need to figure out a way to attach a string (into a hole in the post, maybe, or around the sign), so the yarn doesn’t droop to the ground at the first hint of rain.
If you plan to cross stitch or latch hook directly onto an object, look for something that with plenty of openings, like a fence or a park bench.

2. Sketch and Measure
Draw a rough diagram of your object, then take measurements of each section you’re planning to cover, including height, width and/or circumference, and put them on your diagram. For example, if you plan to yarn bomb a tree, draw a diagram of the area you plan to cover, then measure the circumference of the trunk at both wider and thinner parts and the height of the area you want to cover, as well as the length and circumference of any branches you intend to wrap.
A fabric-measuring tape will work best since it lets you measure oddly shaped objects, such as the arms of a statue or branches on a tree.

3. Start Designing
Decide if you will be knitting, crocheting or using another fiber technique to make your yarn bomb. In creating a design, consider:

4. Start Stitching!
Make the pieces that match the measurements on your diagram. For example, if you have a tree trunk that measures 36 inches around and 50 inches tall, then create a rectangular piece with those measurements. Keep in mind that you’ll be sewing a seam on the object when you install it using yarn and a yarn sewing needle.
If your plan is to latch hook, cross stitch or wrap yarn around an object, do any planning, measuring/cutting and pre-assembling you can.
5. Commence Bombing
When choosing the best time to install your woolly wonder, consider: Will it be easier during the day when you can see what’s going on, even though it will risk your anonymity? Or would it be better to do it at night when no one is around?
What to Bring
Wrap each piece around your object, and use a simple stitch to close the seams. If you need to use several pieces to cover different parts, use a simple stitch to sew all of the pieces together to create the illusion of one cohesive piece.
Thanks, yarn bomber — you just made the world a cozier place!
I have done one. Want to do more.
I’d love to do this, so lovely! And so creative.
I love the color and fun this can bring to an otherwise dull landscape, but yarn bombing live trees is harmful, even if it is temporary. Tree bark doesn’t just protect the tree, it’s a mini-ecosystem. Covering it with yarn is like covering a garden with a blanket. Plus, trees don’t need decoration, they’re already beautiful! Light poles, on the other hand, could use some dressing up! 😁
Excellent points made. Thanks for sharing. I will opt to yarn bomb light posts and other inanimate objects instead if I choose to do so at all. This makes a lot of sense to me.
I just don’t get it. There are so many other things to do with your talents…knit clothing for homeless, make blankets for humans or rescue animals. But knit around a tree?? Why?
to bring colourful joy to people!
This brings a smile to all faces and can raise money for good causes
Thank you for the information.
😍😊😘
These are fantastic. We’re a community organisation and we’d love to brighten our city by using these artistic yarn bombs. We have council permission and now need the know how! Can you help?
We are group of knitters and crocheters that donate our products. What we do, we crochet granny squares, the knitters knit colorful squres, all at the same size, and once in a while, we go and put them together around a trunk: at an enterance of community center, at a school of disabled kids.
So whenever we are between to major projects, we do squares. Good Luck to you.
I have a tree trunk literally like a totem pole no branches as i wait for at least another 5 years for it to dry out. I would pay to charity for a suitable cover to brighten the entrance to my drive – how can i obtain one of these artistic jumpers ? I am in Bedfordshire
that is so cool!
I would like to get more information to do for a project, I am a volunteer at Amaroo Village, Gosnells
This is a great way to spend your free time and appreciate the fact that someone thought to explain how to do it and what to consider. Thanks for reading!
This is vandalism and harmful to nature. There are living organisms on rocks and trees like insects and fungi and bacteria and molds that can be trapped by the stupid yarn. Not to mention the tree itself not needing something on it that could get wet and encourage bad, damaging mold. Not to mention when the sh*t rots it could cause a whole host of problems to the animals like birds. Plus, its just tacky.
The items are not intended to be permanent. They should be removed after a while so should not cause harm to any living thing. I am sorry you find it offensive.

Can you be arrested if caught doing this? I would love to do it.
Hello Cindy,
We would not suggest doing this on property that does not belong to you.
We appreciate your patience during this process. If you have any other questions, please email or contact Customer Service at 888-891-7203.

You are right, but there are also tiny poles and other things that can be bombed around, too. ( I am not a bomber, btw, have a nice Sunday!)
Always get permission from the owners.
