After recreating Billy's rose pattern (I think and thank you Billy) on VisWrap, I am trying to figure out how to space the layout threads. The layout function gives me some measurements, but they do not fall where the layout threads cross the 0 and 180 axises of the wrap. In fact, I can't see where they help at all. How do I figure out these measurements? Does the thread count have something to do with it? For instance I will be using Madeira Polyneon 40. Is there an equation dealing with thread count? I used a spacing of 1.3 in the VisWrap program.

As a secondary question, what is the average thickness of Maderia?

Thank You for any help.

The Visual Wrap measurements are for the centers of each pattern. From there, you need to figure out how many passes you will be wrapping, and space out accordingly. 1mm equals 4.1 Madiera threads when packed (thanks for that one Billy) Also, in the back of Billy's book there are spacing charts for each wrap that help out tremendously.

Hi Bill,

As Mike says, the Spacing List gives measurement for the centre of the pattern. If you click on the 2D Draw button on the Spacing List window it will superimpose the spacing measurements onto the Flat View of the wrap so you can see the result visually . The main assumption made by vizwrap when calculating these spacings is that the pattern is square. In your case you used a spacing of 1.3 (ie the wrap is elongated) therefore the Spacing List won't be of much use!

Rather than use the Spacing List in this case you can print the pattern out true-to-size and then take measurements directly off the printout.
