My wife picked up this serving bowl for me at HomeGoods today. I believe she paid $5 or $6. It does have ridges/texture in the inside and a nice flair so you won't bump your brush handle when creating a lather:
I picked this up at Target. It comes in a set of two in either blue, black, or grey for $1.77. It's a small salsa/dip bowl. BTW, it is dishwasher and microwave safe. This too has a nice open flair to prevent your brush handle from getting nicked. I really like this a great deal:
Last, I bring to you a medium rubber dental mixing bowl. Very flexible and unbreakable. No need to worry about damaging the handles of your brushes when creating your lather. I think I paid $3.75 or $4.75 for this:
Please share your thoughts and cost-saving lather bowl ideas.
