The pattern is crochet. Other than that, and the crochet instructions, it is just a bit vague. It tells us we can use the squares to create a table or dress cloth, chair set, etc. It does not, however, tell us the finished size of the square. It's equally as vague as to the materials. Use any size thread with any corresponding size hook. BUT, it is an attractive motif, should you wish to play around with it !
