Last year I have finished a project and created a pattern for my Scraptastic Infinity Scarf.
After I finished this Scarf, I wanted to create something smaller while using the remnants of yarns from other projects. I started to collect all those tiny pieces of yarn that otherwise might get thrown out, connecting the small pieces together with knots, winding them into a small ball.

Once the colorful ball of yarn was big enough to start a project I CO for a cowl. To hide the knots inside, I have knitted the cowl long enough to fold it in half and join the CO edge with the BO edge by using a technique similar to 3 Needles Bind Off. I have created a photo tutorial for this BO.

The gauge for this project is not really important as you will be using various remnants of yarn.
My finished sample is 28” (72 cm) in diameter and 9.5” (24 cm) high, but you can make it any length you wish to.
Happy knitting.
