These double-ended tunisian/afghan hooks in bamboo are specifically designed for working in the round and for reversible work.
The technique for working in the round is explained in my newsletter for May 2013
For information on reversible tunisian crochet, please refer to my newsletter for March 2013.
As always with tunisian/afghan crochet, you might wish to choose a relatively large hook to avoid your work becoming too dense (try a 1 mm larger hook).
Length: 32 cm.
