OK, as I said, this is kindergarten simple since it came out of my head.
I used Lily's Sugar'n Cream Summer Splash yarn. It's a 4, so a worsted weight, 100% cotton for better aeration of the herbs/spices inside. You can use any weight you want but it will change the size of the pouch.
Size 5 US needles (DPNs or magic loop method)
Cast on 15 st. Divide between three needles, 5 stitches on each needle.
Row 1: Knit Around
Row 2: K1, Inc 1 (I used a bar increase) around
Row 3: Knit around
Row 4: Knit 1, Inc 1 around
Row 5-6: Knit around
Row 7: K1, YO around
Row 8-14: Knit around
Row 9: K1, SS, K1, PSSO, Knit to last three stitches, K2tog, k1 on each needle
Row 10: Knit around
Repeat rows 9 and 10 until 5 stitches remain on each needle (3 if you use a lighter weight yarn),
Knit around for last row to secure loops, cut yarn at about 10 inches, use darning needles to thread end through remaining loops, take needle through hole and secure and weave in end.
Cut a piece of yarn approximately 13 inches (or you can make an i-cord) and weave through holes made with YO. Put in herbs/spices of choice, tie up and enjoy!
If you guys have any questions or notice any mistakes, please let me know. I've never tried to write down anything like this before.
