Overview:
Here’s a further couple of cowls I’ve recently made for cooler weather coming (and for teaching). They are simple tubes worked in Tunisian Simple Stitch (TSS) in the round using a double-ended (DE) hook.

Size:
These cowls are between 21” and 25” around, and between 8.5” and 12” tall. In general, the heavier the yarn, the larger the circumference and greater the height.
This one in 8ply with a 6.5mm DE hook is 11” / 28cm across and 8” / 20cm tall.

Video: Tuula Maaria has a great video on working TSS with a DE hook in the round https://www.youtube.com/watch?v=9H2DduPyEHg&list=PLSG...

Fabric: Use a DE hook large enough that your work drapes. You’ll probably need to go up 1-2mm from the hook recommended for the yarn.

Curl:
This stitch tends to curl/roll which is part of the design here and nothing to worry about. This will happen more if you’re working lighter yarn with a hook only a little larger than that recommended for the yarn. If your working with a heavier yarn & creating a very soft fabric by using a larger hook, your work will curl less and you might want to work your 1st FP into the back humps of the chain for a neater edge as it’ll be exposed. e.g. Here with 8ply acrylic yarn, 6.5mm hook and little curl, I worked 1st FP in back bumps.

Instructions:
Starting chain needs to be at least 22” / 56cm long for a comfy tube that fits easily over your head (but see note on size above). For this yarn/hook combination I chained 80.
Slst join to 1st chain to form ring.
Begin 1st FP by picking up a loop in top of each chain as far as you can.
Turn & slide loops to other end of DE hook.
Slst join 2nd ball of same yarn (or another yarn/colour if you choose) & work RP until a minimum of 3 loops remain on hook.
Turn & continue working TSS in spiral rounds with DE hook until work measures around 9” / 23cm (or desired height - see size note).
Work a slst bind off round. You may choose to use a smaller hook for your bind off for a firmer, neater edge. e.g. Here I used a 5.5mm standard hook for the bind off.
Note: I used 60g of yarn for each cowl. This yarn is divine!
