I made my own hand soap recently. It only took a few tries :) My hands get so dry washing them frequently, despite the "moisturizing" refill soap I had purchased. I would have to apply lotion constantly. I used this tutorial.
My downfall was choice of soap (which actually was pointed out by the tutorial author, I just didn't read closely). Don't use Dove Sensitive skin--it won't thicken. I ended up looking for the brand the author suggested--Yardley. Bonus they had a lemon variety (I love lemon soap). One batch will make a lot of soap, 10 cups worth. It can take forever to gel--like a whole day--and then the texture can be a bit funny and you may want to try to beat it (I wish I had a stick blender) to make it more smooth. Funny texture aside, I love my new soap. It smells better and is much more moisturizing than the refills I was buying.
I have been loving the mason jar trend for a while now. I particularly liked the jar turned soap dispenser--what a clever idea. I could have made it myself (after acquiring some tools and supplies), but bought a fancy lid from Etsy with some of my Christmas money. I didn't have the right size jar on hand at home so found one for fifty cents at the thrift store. I think it's super cute in my kitchen.
