Are you scared of spiders?

are you scared??
These spiders make silk that has been spun and woven into an amazing cloth which is on display at the American Museum of Natural History. My friend sent me this interesting article today.
Hallowe’en is a day where all is not as it seems. The same can be said about projects using the technique of illusion knitting. My first illusion knitting project was the counterpoint scarf {Ravelink} that I knit for my good friend GS, a music major. When viewed from above, it looks like a black and white striped scarf, but when viewed on an angle, the combination of ridges knit and purled into the scarf show a different design. The counterpoint scarf shows a piano keyboard, but you can make any two colour design into an illusion pattern. The scarf was such a big hit, that he commissioned me to knit two more for his friends.

In the spirit of Hallowe’en, I’m going to explain how to make a pumpkin design into an illusion knitting design. All it takes is some graph paper, and coloured pencils, or an excel spreadsheet (for the high-tech knitter).
SPOILER ALERT!!! If you prefer to be mystified by these illusions, do NOT scroll down. Detailed instructions of how to make your own illusions are presented below.
Step 1: Draw your design on the grid.

Step 2: Draw your design, but this time stretch it vertically by adding 3 blank rows between each existing row.

Step 3: Move all orange (contrasting colour) squares up two rows.

How to read this pattern: Main colour is yellow, contrasting colour is orange.
The pattern is knit in 2 row chunks of colour. The first row of any colour is always knit. The second row of the colour is knit only when the chart indicates the colour, blank squares in the second row are purled. This makes a coloured ridge to match the pattern on the right side of the work.
The first 10 rows of the pattern chart would be written out as follows
Row 1: MC K
Row 2: MC K (forms a MC ridge on right side of work)
Row 3: CC K
Row 4: CC P5,K7,P5
Row 5: MC K
Row 6: MC K5,P7,K5
Row 7: CC K
Row 8: CC P3,K11,P3
Row 9: MC K
Row 10: MC K3,P11,K3
etc.
Once you understand the technique, you can design illusion knitting for scarves, mittens, socks, and cushion covers. Remember though, the design will be 4 times as long as it appears on your original grid. Be careful though, if knitting in the round, the second row coloured squares will need to be purled to form the ridge needed for the illusion.
Now, go forth and mystify your friends!
Happy Hallowe’en!
