![]() Most overshot drafts are 4-blocks on 4-shafts.Ĭomputer Software Special Overshot Helps. ![]() Compare this draft to the one on page 50 of Madelyn van der Hoogt’s Complete Book of Drafting.Īnother use for the colored blocks is help in creating profile drafts from overshot drafts. You can look at the balance of the draft by looking for the color balance, figure 2.įigure 4. For example if you add ends to the larger red blocks, you should also add the same number of ends to the larger yellow blocks. Do this by adding or subtracting pairs of ends to each blocks. It is also easy to see how to enlarge or miniaturize the draft. Once you have the blocks identified you can manipulate the draft to suit your project. This mirrors the tabby at the turning points. The number of colored ends at turning blocks is even, the number of ends for non-turning blocks is odd. To weave as drawn in: Look at the number of ends of each color and enter that number of weft picks for the block. Weave-as-drawn-in blocks will produce a draft in star fashion. One repeat is colored and the treadling is added. The ‘weave-as-drawn-in’ weft treadling uses each block the same number of times as the colors appear in the threading.įigure 3. You can also see the mirror points quite easily. The color helps you to see the relative size of the blocks and the balance/unbalance in the draft. Notice how the first and last thread in each block overlaps the adjacent block.įigure 2. Shows overlaping ends at color changes.īlocks are marked with color. The next block is a B block (shafts 2 and 3) Color Yellow.įigure 1. Color the ends on shafts 1 and 2 red until you come to a shaft that is not 1 or 2. Start with end 1, look at the next end which is on shaft 2. In this example: Block A (1,2) is red Block B (2,3) is yellow block C (3,4) is green Block D (4,1) is light purple. Choose four different colors, one for each block. Repeat the threading and color only one repeat. So here is a on screen method for identifying blocks.įinding blocks to create Tromp-as-Writ/Weave as Drawn In ‘block’ treadling:Ĭolor blocks: Instead of circling the blocks – use color. Drafts with ‘pine’ in the name are often unbalanced.įinding the blocks in an overshot threading/treadling is useful for several reasons. Check for symmetry around mirror points and balance draft if desired. ![]() This will catch some typing errors and is a good first check. Use copy and paste and mirror paste when useful.
