Illusion /shadow knitting DIY designs_HK

I have played with excel (and Numbers) before to create charts for various fabrics requiring color separations. My latest efforts relating to this knit group have gone in a different direction; I have also attempted to simplify the technique  in terms of following the instructions for knitting them. This sample began with use of Intwined to create the document and graphs. The first chart is set up with alternate row color striping, color 1=dark, color 2 = light. Blank colored square are used as knit symbol, horizontal dash for symbol for purl stitches. Beginning on light colored, even numbered rows, design is marked in purl stitches

On odd numbered rows beginning with row 1, mark all empty squares in even numbered light colored row immediately above it  with purl symbols

All unmarked stitches throughout the design are knit, whether on the “wrong / right” sides, all dashes are purled, patterning occurs on the second row of each color.To visualize the full pattern one may use the add row below feature to expand the graph (chart below is missing very first row)

Now adding the second row of each color , and grounding stripe (s) at bottom of repeat. Most patterns will start the illusion immediately after casting on with dark color, row 1 above. I was interested for my sample in having a border of sorts on its top and bottom

Intwinded has the capacity for building row by row written instructions for patterns, but there were discrepancies on some rows for these charts, and I opted not to include them.

Another program I have just acquired and begun to use is GIMP; it is free, and now also available for use in Mac OS Mountain Lion. Both Gimp and Photoshop make it possible to design using single pixel pencil and grids to build motifs from scratch as well as gridding of preexisting images. I have a different method for these fabrics using GIMP, easier for more complex, overall shapes. The same series of steps may be used for mosaic knitting (color inversion sequence is different). Below are images generated for a different illusion pattern, I will share my “how to” for designing the motifs later, referencing mosaics and mazes. To achieve such motifs one is drawing in magnification of multiple hundreds and more, there is no way to number within a one pixel space, so these charts as generated are lacking numbers for stitches and rows, one drawback. Another is that this color inversion works only in black and white. One advantage: the proper repeat may be cropped and saved with grid removed in a variety of formats that may be used to import to various machine knitting download programs, and gridded may be used to establish punchcard or mylar repeats.  Screen grabs of magnified charts were saved, and are shown below. Black squares represent purl stitches in second row of each color. First row of each color is always knit, not represented in these charts

the red squares are guidelines for no color inversion rows, the yellow ones isolate the repeat

Feb 18, 2017 I have recently become curious about creating illusions such as these in crochet, am developing ideas and returned to this chart. The image below is intended to have symbols and notes superimposed on it. It shows the tiling in a different way, so I thought I would add it to this post as well. Repeats are highlighted with darker borders. The repeat on right needs to be trimmed if the goal is to achieve matching edges. Row counts on right would differ in knitting, the plan is to execute this pattern in Tunisian crochet, which handles rows in a very different manner than knitting or standard crochet.
