Day 8: What’s your most challenging project?

My most challenging project was probably the mitts I have recently finished for my Granny's Christmas present. Though I've done fingerless mitts before, doing colorwork like this was a challenge. I made Lusekofte-sque Mitts in Cascade Superwash Sport Blue Velvet and White. I loved this color combination. They are a bit smaller than I would have liked because of the tension of the floats of white, but I still adore them.
