Two pairs of leg warmers and four hats done and the quick fix of chunky wool and large needles has worn off. Time to get back to another jumper which I can start and then put down for another year or three before finishing it.
I had been doodling with various pattern ideas on some knitting graph paper when a light bulb moment occurred. Spreadsheets! Absolutely perfect for creating knitting patterns. The cells can be scaled to match the tension. And more colours than I could ever use.
The above is my first attempt and I have started knitting it.
But I am choosing my colours as I go along to use up odd balls in various shades of blues, pinks and purples. And I don't think the squiggly pattern section will work in double knitting - the detail won't show up well enough, more of a chunky pattern so that bit will be changed...
