I have an 8 yard double width piece, so what it means, if I understand the graph in your book, is that I would only be able to make a kilt for a smaller-than-usual man..hmmm. Maybe the 5 yard double width Duncan would be a much better choice after all! I will need to ponder this! And I do have experience with the Duncan..chuckle. Since his waist is larger than his hips I am making another tubular kilt, apparently! Thank you for the input. I think I see where we are going here. Mary
