I'm wanting to make little sachets to hang in wardrobes, etc., to make clothing smell nice

I've done a search on Craftster but haven't found anything exactly like the things I'm thinking of.
Making the little stuffie itself is the simple bit, it's the scenting (and keeping it scented) that's the problem. The first thing I thought of was essential oils, but I'm concerned that they'll a)smell too strong to start with; b)the scent will wear off quite quickly, and c)the oil will mark the fabric.
I know I could use lavender flowers for a more subtle scent, but I'm not overly keen on lavender - I'd like to have a wider choice, to be honest.
Any suggestions (or pokes in the direction of relevent threads) would be most appreciated
