I was inspired by the mosaic from Ravenna’s Mausoleum of Galla Placidia: photo. I charted 3 variants: with band size 6 stitches, 5 stitches and 3 stitches. Total width correspondingly: 58, 49, 29 st. (the photos show 5 stitches band)
For the sides, back and sleeves I used “Crenellated Pattern” from “A Fourth Treasury Of Knitting Patterns” by B.Walker.
The pattern calls for 8 different colors + one for background.

The PDF file you are buying does NOT contain knitting instructions but these 3 color charts and Crenellated pattern chart. Also there are photos of the sweater.

Some guide lines how to plan this sweater:

1. You must be an experienced knitter.
2. Choose the yarn you want to use.
3. Make an one-color swatch.
4. Calculate total number of stitches for the desired sweater’s width according to the achieved gauge.
5. Divide this number to 4 and see to what color chart it is close: 58, 49 or 29 stitches (29 st is good for the children variant).
6. Recalculate the remaining 3/4 of stitches, adjust the number to the symmetrical use of the basic body pattern.
7. Subtract 10-15% for the rib.
8. Knit the rib, increase the stitches number, knit the colorful part, then knit the rest of the body, joining it on the fly or leaving for seeming after blocking.
9. Sleeves and neck I leave at your discretion :)
10. Good luck and please share your project!

P.S. That’s not the exact mosaic pattern since I removed the white lines. But the full mosaic pattern is also presented on Ravelry: Ravenna.
