This is my biggest and most complex illusion design to date (as of November 2013). That doesn't mean it is more difficult to knit. It is just big and takes a long time. It has 300 stitches and 247 ridges (494 rows) of knitting.
The illusion is based on The Three Graces, by Peter Paul Rubens. The original painting, which is now in Museo del Prado, Madrid, was painted around 1630.
The three Greek goddesses are Euphrosyne, Thalia and Aglaea and were referred to as The Charities in Greek mythology. They are usually said to the daughters of Zeus and his third bride Eurynome though some legends link them to other parents.
When you look at the knitting from in front you only see narrow stripes. The image appears when you look from the side. Photographs cannot convey the WOW factor of illusion knits. Follow the link to our web site to see videos of some other examples - though that is still not as good as seeing them in the flesh.
You can use any weight of yarn but I recommend using something fairly fine or the finished piece will be enormous. I used King Cole Big Value 4 ply in Opal and Cream at a gauge of about 6 stitches to the inch. Using a slightly thicker yarn would make it the ideal size for being a bed-covering.
The pattern has various versions of the chart, including one intended for tablet users, to make it as easy as possible for you to make this without ever losing your place.
