If other colors appear in my supply it tends to be in multi-color yarns. Camo, red/green/white, red/blue/green/yellow, etc.
My completed projects definitely show this as well. So many of them include red or blue with some sort of neutral or black/grey combo. Need proof?
From my red, black, and white collection there's the red and black fingerless gloves, my Cranberry Cloche, and the Long Stocking Cap.
Then from my blue and neutral collection we have the Pretty Puff Slouchy Hat, the knit scarf for my niece, my Striped Knit Beanie, and my Crocheted Flowers.
Looks like I'm in need a of a color challenge!
