While I am weaving on this overshot draft called "Wagon Wheels", I thought I would tell a little about weaving on the diagonal. Another term is to call it "tromp as writ". A Handweaver's Workbook by Heather G. Thrope says: "This simply means that the harness (shaft) combinations found in the written draft are taken for the tromping of it".
Here I am showing the block that I have just finished. It had 8 pattern picks and 8 tabby picks.
The next block to weave is always to the left of the one just completed. It shows me three threads, so I will weave 2 pattern picks and two tabby picks. You always weave one less than the number of threads shown.
