Yes, I did use the Silhouette again! Couldn't find an old-fashioned bathtub design I liked, but this one is pretty, too. Used a pretty font on the top to let Brian know not to eat it. Bought the container from Amazon. It's plastic. I really didn't want a glass one in my bathroom.
Here it is prior to filling. Notice that the bath salts lettering is not centered with the design. Now, if I can just remember this lesson for the next time.
I looked at a dozen recipes online and decided to go with the straight Epsom Salt, essential oil, and coloring. Some people put in dried lavender buds. Having purchased a few bath products with lavender and seaweed in the past, I know I would not like them in my recipe. Plant matter in bath stuff is a triple pain for me. First, I don't like stuff floating around me in the tub. Second, I don't want it clogging up the drain. Third, I really don't like having to crawl around the tub afterward to get all the little pieces out. No lavender buds in my bath salts.
For all those bath product fanatics out there, gather up your tools and such,
and give it a try. There are a ton a recipes available online. One tip not usually mentioned for getting the oil and coloring well mixed is to keep grinding the mixture back and forth between your hands until all the dark specks of coloring are gone. If you prefer not to have food coloring on your hands and nails for days on end, latex gloves are a must, too.
