The operation is so simple that even elementary school children can joyfully knit colorful tubes in various colors. After guiding the yarn through the lower and outer yarn guides according to the instructions, it is simply allowed to slide into the middle shaft of the knitting mill. Now, only the hook sequence needs to be observed during the first round, and from there, you just need to crank. Weighed down with a provided weight, the finished knitted tube slides out of the knitting mill at the bottom and can be further processed once it reaches the desired length. Firmly twisted wool is best suited for needle sizes 3-3.5 mm. A detailed instruction manual is included in the package.
