Dena,
I thought of you last night, after getting home really late. I knew that yesterday you were picking up Nat's ashes and that it was exactly one week since that precious Angel's passing. I was trying to think of a way for you to keep them, if you don't want to scatter them. In California, we have these little "do-it-yourself" Pottery/Ceramic places. One selects a unadorned object, say in this case an Urn. You then decorate/paint the exterior surface with whatever you want and then bake it in the on-site ovens. You could make the exterior adornment personal to you and your precious baby.... perhaps a poem, a beautiful picture of her.... you're so wonderful with words Dena. Once it's finished, inside you could place her remains, maybe a copy of that beautiful video tribute you made, a special toy, like her LammieDoodle, anything that is meaningful to you and her. You would then have something tangible to remind you of and commemorate your baby.
Here is a link to a studio called "Color Me Mine":

It describes the various steps to creating your own personal ceramic. Perhaps you could find a similar facility in your area.
Just an idea for you to mull. Dena, I want you to know how often I think of you. I hope each day continues to get easier. Just keep reminding yourself, the wonderful quality of life you managed to give Natalie in the short time she has here on earth. Hold onto the memory of all the love and care you showered her with. And hold on too, to little Gracie.... she too has such a special purpose - she was the perfect playmate for Natalie, and now she is a comfort to you, she cannot fill the void, but she lessens its dimensions.
Hugs to you my dear friend,
Lauren
