Well I try not to have too many 'wip's' [works in progress]on the go at once and then I see something that completely captures me and there goes that plan.
I saw rainbow blanket on the Purl Soho website. You can buy the kit from them for a mere US$780.
That seemed a little excessive for my budget and then I remembered the plain skeins I'd been stockpiling from our nearby Milton Mill Shop - at NZ$12 for 200g they were a bargain. They are a fingering weight sock yarn - 80% merino 20% nylon. I think I have enough to make the blanket and if not then my sister has a few spare - so it should work out.
Of course with over 40 colours there is a little dyeing required- and my skills will have to improve to actually get the colour I'm aiming for. Given what is involved I decided it should be a year long project.
Next I ripped it back and measured how much yarn each part took so I will know how much to dye.
That seemed like enough for the first week. Next I'll start to think about the dye colours.
