Go from this:
Small amount of worsted weight yarn. I used cotton (Lily Sugar & Cream) because I think it will last longer and absorb the heat a little better.
G size hook and needle for weaving in ends
ch = chain
sc = single crochet
sk = skip
Round 1: Chain 32, join to make ring.
Round 2: Ch 1, sc around, join.
Round 3: Ch 1, sc in first sc, *ch1, sk1, sc* around, join.
Round 4: Ch 2, *sc in ch1 space, ch1*, repeat around
Repeat for 7 more rounds (for tall size - you can add more rows if you drink taller cups)
Last round: Ch1, sc around. Finish off and weave in ends.
That's it! Now go enjoy a cup of "eco smart" joe!
