I bought all my supplies at The Portland Homestead Supply Co. (except for the little Altoids tin). If you are ever in Portland, specifically in the Sellwood neighborhood, the store is worth a visit. They have all sorts of homesteading type supplies, including soapmaking, canning, and all things urban chicken raising.
I also made a lotion bar, using the same ingredients (beeswax, shea butter, and sweet almond oil) but in a 1-1-1 ratio, also scented with lavender and peppermint essential oils. I LOVE this bar! My 10-year-old, who has always had a touch of eczema at his elbow creases, has also been using this lotion bar and loves it too.
