I have reworked my pattern in different yarns:

CONCEPT by Katia - Caliope - 100% cotton yarn - 114y/50g (105m) - Shown in color 67 quantity: less than 1 ball

Phil Coton 4 by Phildar –100% cotton yarn - 93y/50g (85m) - Shown in color 121 ecru

2 sizes are available:
circumference: 20”-21” (51-54cm)
22”-23” (55-58cm)

Both are knitted in the round with 2 sizes of circular needles. The yardage is of course not important: less than a skein.

The pattern is written in Standard US terminology. It includes written detailed instructions with many pictures and as usual I always help if needed.
