WORK IN PROGRESS
Machine knit hems 2 and Machine knit hems 1 discussed picking up stitches to form hems across full needle widths.
“Wisteria” meets hems introduced small hems in combination with short rows. 
Slip stitches may be formed and brought to the front of the knit, they tend to get elongated in proportion to the number of rows for which they are held.
Single bed tuck and slip stitch fabrics 2: adding color presents some of the visualizations for and distortion of horizontal stripe patterning resulting from frequent color changes.
Slip stitch patterns with hand-transferred stitches, single bed looks at methods to bring the elongated slipped stitches to the front of the knit.
With a start on the left and an even number of rows in each horizontal stripe allow for knitting away from and back to the color changer consistently.
The first sample, plotted in a spreadsheet, 
is purely a hand technique, no programmed clues, but a custom needle tape can be colored in to aid in correct needle selections.
In knits where stitches need to be held and not worked, one method used is to knit specific stitches back to the A position.
If using the color changer each stripe must be formed by an even number of rows with selections from left to right.
The repeat is 40 rows in height. I chose to continue the hems on both sides of the swatch.
Following the chart, knit 8 rows with color 1, end COL
COL: change color to 2, using ravel cord knit through stitches marked with white columns in the chart back to A across the row (1)
knit 4 rows, 9-12
return to COL, hang a hem on every needle
COL: change to color 3, knit 4 rows, 13-16
return to COL
COL: change to color 2
knit 4 rows, 17-20, return to COL
hang a hem, I chose to pick up the stitches in the row below the hem color (images 2 and 3), bringing needles out to E as I worked across the row, watching for any dropped stitches on each side of the ravel cord
COL: change to color 1, using any preferred tool reach behind the floats formed in the areas of skipped stitches, lift up the stitch held by the ravel cord back onto the needle bed across the row (3), knit 8 rows with color 1, 21-28, end with COL
COL: change to color 2, repeat the process for the alternate groups of needles, with color changes and action occurring on rows 29-32, 33-36, 37-40. 
Another method for creating the long stitches on the knit side is to use short row technique, setting the knit carriage for holding.
Again, knitting is planned to start from the left side, using each color for an even number of rows. Three stitches were added beside the needle tape markings on the right.
Plotting the actions in a spreadsheet, and planning knit with no held stitches on either side. Symbols, numbering, and note keeping can be developed as preferred in personal DIY.
During knitting keep an eye out for stitches on either side of those placed out to hold, they may have a knack for dropping.
After the choice of base knitting, begin pattern with COL and color 1
knit 4 rows, returning to left, hang hem on every stitch
COL change to color 2, knit one row to the right
COR set knit carriage to hold, push first groups of 3 needles out to hold as indicated with the white cells in chart, and the blue ones on the needle tape, knit back to the left
COL change to color 3, continue with machine set to hold, knit 4 rows
COL change to color 2, cancel hold, knit 2 rows
COL change to color 1, knit 4 rows, hang hem on every needle
COL change to color 2, knit one row to the right
COR set the knit carriage to hold, push the alternate groups of 3 needles out to hold as indicated with the white cells in chart, and the blue ones on the needle tape, knit back to the left
COL change to color 3, continue with machine set to hold, knit 4 rows
COL change to color 2, cancel hold, knit 2 rows
COL change to color 1, knit 4 rows, hang hem on every needle
Continue in pattern
