I insufficiently well know English to explain crochet the flower pot holder pattern, but I have some photos with this process - http://picasaweb.google.com/kudepihha/Camomiles?authkey=Gv1sRgCJ2v3IeVmf3P0QE# . I hope that it will help to understand.

From the middle crochet 12 dc, then a row 2x2=24 sc, the following row without additions. In following a row needs to add in regular intervals 6 sc, a row without additions, from * to * to repeat till the necessary size.

Good luck,
Inga
