What is necessary:
If you’re a beginner my advice is start with needles 3mm or 3.5mm, but you can consult also with the seller about the choice of yarn and knitting needles.
This is my knitting needles. You can see part where is mark size of needles
Better use hook with a wooden handle. It is much easier. Usually i use hook size 5mm and yarn size 3.5mm. You will see in tutorials.
This needle we used to pull in the ends. So make sure when you are working to leave longer the ends.
If you have everything ready, choose some of the tutorials and
you can start easy …
