Glass Jar Covers - I remove jar metal lids and replace with crochet covers (those shown above are not mine). Takes just a few minutes to crochet a top cover and so pretty. Perfect for room deodorizer. Fill jar half-way with fresh baking soda, then add a couple drops of your favorite essential oil. When scent fades just shake to refresh. Scent lasts a long time. No chemicals or masking odors.
