There's an MKAL in progress on Ravelry where some of us are trying to knit the Ultra PimaRose Trellis Shawl Vest from Cascade Yarns.
There's a hand-written chart available from Tonyanelson's notebook, but it's a little hard to read... so I managed to duplicate the chart in Intertwined Pattern Studio. Click on the image below for a larger view.
A few explanations are in order...
The pattern is a multiple of 20 stitches plus 2. Each repeat is 20 stitches, but the repeat does *not* apply to the same set of stitches in every row. I've colored the two center repeats yellow and green so you can see where they start and end. If you compare rows 1 and 3, you'll see that the first repeat on row one starts with the 2nd stitch, but it starts with the 3rd stitch on row 3.
You'll see some stitches colored pink on the right and left. These are stitches that are added to the beginning or end of the row... i.e., before the first repeat or after the last repeat.
Lastly, you'll see some stitches colored blue on the left. These are stitches that disrupt the pattern repeat. For example, look at row 21. The pattern repeat ends with k3tog. That's impossible when you only have 2 stitches remaining. So the yo k3tog at the end of the pattern repeat has been replaced by k2.
The stitch key is shown to the left. Click on the image for a larger view.
The DAK file is also available for DesignaKnit users who want to do their own tweaks.
