I had the yarn but I didn't have any knitting loom so I decided to make them with cardboard!
This is the big round one but you can make any loom you need this way.
It's very quick to do, consider that I was able to make this loom and knit a whole hat in less than a day!
Cut the cardboard following the lines you have just traced and keep the round strip.
You will probably need 2 or 3 cones so make more than one.
You will need 41.
Once you are done cutting them, glue each cone on the round cardboard strip separated by a distance of about 1cm (0.39 inches) using hot glue.
Now you can either paint it or leave it the way it is, your knitting loom is ready to be used!
