I always add a little sachet with dried lavender with the dolls. It smells nice and it keeps away the moths from your woolens. Although I love lavender, especially fresh in my garden. I'm not very fond of dried lavender alone.
So I did some searching on the internet for natural mothballs. And I came across these ingredients:
Lavender, spearmint, thyme, rosemary, cloves, cinnamon and cedar shavings (this little sachet doesn't have the cedar shavings, but the next ones will).
It smells so delicious!
I use the same amount of every herb and a little less cloves (cloves are very intense) but just add the amount you want to make a lovely smelling natural mothball.
Of course there are more herbs you can use to make a chemical free mothball like tansy or woodruff.
I still have a lot of preparations to do for the seminar. Stress is in the house ;)
Have a wonderful week!
