Thanks for the tips! I will definitely keep my eye on them. The recipe made 12oz jars which these are, but I had left over in the bowl that didn't fit in the jar, so I'm going to have adjust the recipe. And it called for 2 Tbs of fragrant, which I thought was a lot, considering the size of the jar. The aroma beads I ordered should arrive today, I'm going to try those too. MTT - the cardboard inserts you use, you can buy them that way or do cut them yourself? Also do you guys put a self adhesive round sticker on the lid over the vents to keep in the fragrance? Thanks!
