With the approach of fall and winter once again, the post with Seasonal knits inspired by published repeats 1 was discussed in Ravelry.
This share adds to the library of collected repeats, aiming for daily updates.
When choosing any design, view or print the tiled image or selected portions magnified as much as possible, after giving the eyes a rest, before committing to knitting, which can sometimes be followed by disappointment.
Recently, I have begun to use the 930 Lace Carriage for preselecting needles in B position, moving toward the knit carriage, and then removing it, instead of switching to slip stitch for a free pass when needed and risking confusion in returning yarns to their proper position or forgetting to switch cam buttons for proper technique.
Charts will be provided for designs suitable for punchcard use.

Developing DIY repeats for color striping or with color-inverted tiles can begin with any motif drawn in repeat with areas where pixels repeat in even numbers across rows or columns, lining up horizontally, vertically, or both.
If the goal is to knit a single bed fair isle, consider float management to secure the 10 stitch floats, as in this case, alter the repeat, or simply choose another.
There are several approaches for generating new designs from those already developed. One is to begin with a tiled version, choosing possible breakup points, which are highlighted here in magenta. 
The manually isolated repeat, 27X54, with the bottom half color-inverted.
The design, drawn in repeat X 3, formed alternating color inverted horizontal bands with pairs of pixels at the tiling vertex.
Making the choice based on personal preference to eliminate the extra pixels, using ArahPaint mirror X-1, 53X54.
Color inverting each quarter for pattern blocks, 53X54,
mirrored X-1, 52X54
A slightly different approach, starting with the 27X27 file, undisturbed, 
draw in repeat X2 in height, and using rectangle select choose the part of the design with the double row of pixels as the point for dividing the image into 3 segments, 
using rectangle select and colors > invert all, to form the new 27X54 file, for the horizontal repeat.
The same file drawn in half-half-drop repeat for alternating tiles of the pattern, 54X54.
The 27X27 doubled in width, 54X27,
with the center 27 pixel section color inverted,
for vertical stripes.
Adding a few pixels for float control?

The proof of concept, knit on 61 stitches.
Punchcard knitters can also add holes to specific areas for float control, such as in the 24X22 repeat shared at the top of the post.
Card programmed designs are centered, mirrored horizontally, and repeated in fixed locations across the needlebed. The needle tape markings serve as guides.
When making pieces, if the goal is to place the center of the design other than in the default location, one solution is to move the work to a different place on the needle bed; the other is to shift the motif before punching the card.
Here, the chosen design is drawn in repeat to 48X22, the center segment is isolated, and cropped to the new 24X22 motif, shown on the right with the new holes to punch highlighted in magenta.
