Wanda! I LOVE the mummy!! Not too raggedy at all, I personally am in love with the raw edge applique look. Such a great idea!!!
So far as buttons and ric-rac. Flat items like the ric rac or ribbon are fine (won't bother anything when quilting) 3-D things like buttons, just make sure they are on their own strings so people could potentially take them off if they didn't want them there when quilting.
Cheers!
