After the first few inches weaving this problem really stood out. It was especially apparent in the repeating middle section. Take a close look and you will see what I mean.

If you look at the photo accompanying the draft in the Davison book you will see that sample also shows this problem. I guess this is a lesson to look very carefully at sample photos as well as at drafts. It's dangerous to make assumptions.
The Davison sample photo is curious. It is so different from other samples in the book. It appears to be an entire woven piece and clearly shows crease marks. This made me wonder if the draft had been copied from the woven article and not actually woven by Davison herself. At the top of page 186 is a notation "Adapted from Caroline Halvorsen's Page 106 - No. 185".
Last week I did a search and discovered a book by Caroline Halvorsen and placed an order for a used copy. I do not know if this particular book is the source of inspiration for the Davison draft. But I aim to track it down.
Reading the "Understanding Overshot" chapter in The Complete Book of Drafting for Handweavers by Madelyn van der Hoogt it looks as if this draft may have originated in an abbreviated form. If you read the section "Variations in Drafting Format" on page 41 there is a clear explanation of how an unbalanced draft could occur.
When the Halvorsen book arrives I'll let you know what I discover. Then I will show you my solution to the problems with the Davison draft.
