Crochet Trelyss Slouch Beanie Pattern & Video Tutorial

Happy March! I have a fun pattern for ya'll today! We went camping recently and I found this yarn in our trailer and wanted to crochet something with it. As I was making it, I remembered starting a similar pattern years ago and scrapping it. It's the case of too many projects, not enough time.

I'm glad I finished this one. Mostly because I wanted to record a video with some new gear I bought. Similar to yarn making me happy, camera gear makes me happy too :) I'm upgrading my set-up and was excited to try some things. So bear with me while I test a few equipment out....

Repeat Row 2 until desired circumference ending on the same side as the beginning tail. Measure brim while slightly stretched. See chart above chart for standard circumference sizes.

Seaming the brim

With short ends together, sl st through the “chain” end of the brim and tbl of the other end of the brim. Flip brim inside out so the seam is on the inside.

BODY | Switch to larger size hook

Round 1: Ch1, 1sc around the brim in multiples of 6 sts. Sl st to the 1st sc.*

Note: You can choose to work in a continuous round without joining. Place a marker on first st to track the beg of the round. Round 1 in the rep is sc sts around. The repeat for Round 1-8 will just be sc sts around.

Round 2-3: ch1, 1sc in every st around. Join with a sl st in the first sc st.

I found these affordable and pretty Faux Fur Pom Poms on Amazon that I used in my tutorial. It saves me so much time but if you want to make your own, I've provided links for 2 tutorials.

Pom Pom (optional)

Using an extra-large pom pom maker (or desired size), make pom pom by wrapping yarn around pom maker until full or as thick as you’d like and attach to beanie.
