Differences between illusion and shadow knitting

Dear friends! What did prompt me to write this article? Clicking the link that promised to teach shadow knitting, I saw pictures of shadow knitting, but description of the illusory. In fact, they’re totally different knitting techniques. I confess, that on the main page of my site illusory knitting is also called as the “shadow knitting”. Let's look at these two such beautiful knitting techniques.

What’s the difference?                         Face view
         

Shadow knitting

Any picture in shadow knitting is knitted with one-color yarn. Therefore, for this type of knitting any filet chart, stencil or monochrome picture is acceptable.
1.    Picture is knitted on the knit row with purl stitches.
2.    Background is knitted with knit stitches.
3.    On the backside all stitches are purl.
4.    One line of the chart represents two rows.
5.    To see one line of the picture, you need to knit two rows.

Illusion knitting

Any picture in illusory knitting is knitted at least with two yarns of contrasting color. For this type of knitting it’s acceptable to use filet chart, stencil or monochrome pictures as well as in shadow knitting. For images with halftones it’s just harder to draw charts.
1.    Picture is knitted on the purl row with knit stitches (with a picture color).
2.    Background is also knit on the purl row with knit stitches, but with a different color.
3.    On the backside there’re both knit and purl stitches.
4.    One line of the chart represents two rows.
5.    To see one line of the picture, you need to knit four rows.

As you can see, just one point is the same for both types of knitting. Detailed description of the illusion knitting is on the page Getting Started
And now look at the products knitted using these methods.

          
The yarn and needles thickness are the same, but the paw made using shadow knitting is thicker than the illusion one. The picture knitted by shadow knitting can be seen from any angle, and to see the picture on the thing knitted by illusion knitting you should look from the certain angle.
Perhaps, this is the main difference.
Haven't I persuaded you yet? Then try to knit the undertones (as shown on the example) using the shadow knitting ;-)
