This is not a very professional pattern, i have just written while crocheting, i used a yarn i had long time ago i lost the label and all the info of the beige yarn, but you can use any yarn you want, and if you want the size to be like mine then use a yarn that fits a 3.5 mm hook.
I used a dc Tunisian stitch, if you like the texture and want to crochet it, just search on youtube “ tunisian double crochet tutorial” and you will find it and it is pretty easy to follow :)
You can apply this pattern to a normal double crochet stitch.
I used for the frame a super bulky yarn made of (67% acrylic, 14% wool, 10% polyester, 9% mohair)
And i used a normal sc crochet stitch and a 3.5 mm hook, you may wonder it is a super bulky yarn why 3.5 mm, it is because a larger hook size will make it hard to crochet through the beige yarn

Abbreviations
ch = chain
dc = double crochet
sc = single crochet
tog = together

Materials
Himalaya mountain (Super Bulky), 3.5 mm tunisian hook( used with beige yarn), 3.5 mm normal hook( used with the super bulky yarn)
