For your MIL how about just some 'color' in general. Go with either a pallate of blues or yellows or anything really. Pick some fabric that is cozy yet fun and timeless. I think all apartments are that blah brown and beige and white. Accent pieces can be such fun to spruce up the place (I know I have fun taking a white and tan apt and making it colorful and mine).
So i have nothing really done for the holidays. I have 2 blankets that can be gifts or HH.
Yeah,maybe I'll just "give"her some color.
