Rose Choker

I have a membership of MOPS(Mothers of Preschoolers). At each meeting, we do a little craft.
I made this choker from the leftovers of those crafts adding some scraps of my clothes.
I am giving this to some friend, for it matches her much better. (Actually, it doesn't match me at all.)
Should I never tell her where all those materials were, and keep my decency?
