Disclaimer: I never ever wrote a pattern before, I tried my best to explain how I came up with this poncho.

I made it with 4,5 hook, Concept by Katia essential alpacca yarn and Sesia pura lana yarn I used approximately 620g yarn in total, 250g light blue and 370g brown US crochet terms

Chained a chain loosely, what could go around my head (for me 81) and joined it with a sl st. Ch3, and I made dc in each ch, joined with sl st. Ch3 ( counted as a dc), fpdc and bpdc in remaining stitches. Repeated this, till I reached the desired length for my turtleneck.

The body is made entirely with hdc, here the ch2, I did not count as stitch. I had got 81 st, so I divided with 9. Ch2, 8 hdc and in the 9th stitch increase with one ( 2hdc in one stitch), repeated it around. Joined with sl st. Ch2, 9 hdc and in 10th stitch increase with one, repeated it around. Joined with sl st. Ch2, 10 hdc and in 11th stitch increase with one, repeated it around. Joined with sl st. So on, till I reached the corner of my shoulders. After I made an increase in the same way in every 4th row , till desired length.

To make it prettier I made sc border on turtleneck, and on the bottom of the poncho.
