Linux scarf from Ulla
I’m adding this to my project list, right after I’m done with my sister’s shawl and a nordic patern hat for me.
Illusion knitting is based on repeating throughout a set of stripes alternating 2 stockinette stitch rows in the foreground colour with 2 garter stich rows in the background colour. On RS, this will create a flat fabric for 3 rows followed by a bumpy one (the bumps caused by K on WS). When you get to knit the foreground pattern, you reverse this order: the background colour will be knit flat so that the bumps knit in the foreground colour can emerge. As a result, on RS, a slanted view will reveal the full illusion since you only get to see the bumps. From a frontal view, however, you will only see stripes, albeit slightly irregular in some places.
