Make laundry smell strong and long lasting?

So I ve been experimenting with my laundry for a long LONG while now. I ve used several different kinds of products and found that Snuggle blue sparkle works the best. But the smell kind of just fades away when I set it in with my other clothes in the closet. I never wash my clothes with my towels, I set the dryer on air fluff so there is no burnt smell from the dryer.
What are you tips to making my clothes smell stronger and last longer.
