Oh, you do have lots of purple in that stash on your shelves!! I am getting ready to FMQ a large black and purple quilt myself, although I don't choose huge amounts of purple. I do have favorite colors that I always love the most, yet I so love COLOR that I like to work with all colors. And my clothes closet always has lots of the same color tones, so I guess I like to wear the same colors nearly all the time. But, if it makes you smile, go for it!!
