The 3 cols. Roses Patt. is a favourite of mine, I haven't got a 965 so had to copy all the pages from the black&white graph from the 965 Stitchworld Book II.
Pattern 851 consists of 90 sts.x390 rows in separated rows! Can you imagine the time it took to draw all of that dot by dot into Designaknit, then colouring in all the rows according to the numbers alongside the graph?
That was many years ago; wouldn't have the patience now. At several points in the pattern the col.sequences changed so there is no distortion in the pattern.
If one looks carefully, there are a few of these type of separated patterns in this particular book where the col.sequences are not in order of 1,2,3 or 1,2,3,4. for the same reason.
All of these are done in what is generally a Brother default separation referred to in Design-a-Knit as B-separation or otherwise also known as Sandwich-separation, because they start with 1 row of Base col., followed by rows 1&2 of first contrast, rows 1&2 of second contrast,(in a 3col.patt.) finished 3 row sequence is row 2 of Background col.
Next sequence follows in the same order! Check the Picture (click on it for a larger view).
So the contrast cols. are "sandwiched" between the Background colour!
