What’s Blendoku?  It’s an intriguing free app that sharpens your color management skills.  Should disaster strike and you find yourself without your knitting (gasp!) it’s a fun way to sharpen your skills for setting up smooth color gradients for your stranded knitting projects while you wait for the cavalry to arrive with your yarn.

Handheld color gradient practice that can translate into Fair Isle knitting skills

Be warned: Okay, yeah, it’s also a black hole for time – too much fun!!
