The pattern uses the Tunisian reverse stitch (R) and Tunisian knit stitch (K).

The larger size hook is the Tunisian hook for making the dishcloth, the smaller hook is for edging the finished dishcloth.

Two colours of cotton are needed and the pattern states Coats or cotton worsted yarn:
100yds / 91m #1088 Blossom Pink (MC)
40yds / 37m #1021 Linen (CC)

All the patterns in this book were designed not to curl.
