Patterns for Purchase
A New Angle
3D illustion for an afghan blanket or wall hanging.
Curve of Pursuit
It may look complicated but, if you can knit garter stitch, you can make this.
This afghan is based on a design sent to woollythoughts by the famous Oxford mathematican Sir Roger Penrose and is named in his honor.
This is design is much easier than it looks. It is worked in one piece, using one colour at a time and with a maximum of around one hundred stitches on the needles. There is a tiny amount of stitching to be done.
Fibo-optic Afghan / Wall Hanging
Fibo-optic uses the Fibonacci Sequence in two directions, in each of the three dimensions, to give the illusion of a large flying cube.
This design by woollythoughts is nowhere near as complicated to make as you may think. If you can knit garter stitch, you can do it.
Optical illusion blanket knit with illusion knitting. There are never more than 20 stitches on the needles at any time. Most of the joining is done as you go but there are a few small seams left to be stitched.
Optical Illusion Afghan Graph Chart
I can’t find a picture of the finished afghan but it looks like it would be spectacular. The designer states that the actual graph size is 150x200. If you would prefer different stitch/row dimensions, let the designer know.
