Heat packs + rose petals?

[bubbledragon.livejournal.com]

Ok, so I've made microwaveable heat packs before. And it just so happens that I have enough fabric and fill to make one more. About two weeks ago, my fiance sent me roses, and they're wilting now, but they still smell absolutely wonderful - actually more so now than before. So. I want to preserve them. I did hang some to dry, but what to do with these? Would it be feasable to just add these petals to the flax seed I use in a heat pack? I think that would just be grand! Any other suggestions? They're obviously not fresh, so I don't think rosewater would work so well, though I'd like to hear directions on that for future reference.
