Yarn: Cascade 220 Heathers yarn in:
2425 provence, 2427 Glamour, 2431 chocolate, 2435 Japanese maple, 2437 kansas, 2440 vinci, 2442 fog hatt, 2444 flame, 2453 pumpkin spice, 4010 straw, 8013 walnut, 9332 sapphire, 9491 greystone, 9562 coffee bean plus some oddments of yarn in my stash

I started out making this with the plan that it would be a throw for an ugly sofa but after my husband built me a storage bench for my yarn stash I needed a cover for the cushion and decided this throw would be better as a cushion cover. The top is crochet which extends a little way underneath where I’ve sewn it to a rectangular piece of fabric.
