Skill level: easy/intermediate
There are only two stitches which could be difficult - make 5 out of one stitch and knit 5 together. I explain with photos how to do it, and at the end it is very easy.

Stitches used:
sts - stitches
k - knit (stitch)
p - purl (stitch)
m5 - make 5 stitches out of one
k5tog - knit 5 stitches together

Materials:
•150 gr worsted weight yarn (MEDIUM 4)
(I used 50% wool, 50% acrilyc yarn)
•circulal needles US 10 (6mm) or size needed to obtain gauge (though you have to work in rows and not in rounds, I suggest to use circulal needles as the piece is quite wide and you need space for it)
•tapestry needle
