I paid £20.40 for 6 balls of yarn. if I type this into the relevant box on this page it loses the value.
Increased to 125 sts aiming for an n x 5n wrap.
10th June 2012: Am frogging to reknit as an n x 3n wrap having seen the dimensions that it is knitting up.
2nd July 2012: All finished bar sewing in ends, blocking and photography. Will write this up at some point and decide how much to charge for the recipe – or whether to make it free. I will hopefully draw some diagrams to help explain the maths and/or provide a table of examples.
