What size soap mold?

[Momof2!]

Okay, my husband is going to make me a rectangle soap mold. I haven't made soap in a while but I make it in a blender. What size mold should he make  so that when I pour the soap in it the soap will come to the top or near the top so the bars will look like bars when I cut them and not like little nuggets. Does that make sense? I want to be able to cut it into bars but I can't remember how much soap is made in a blender? 2lbs? I'm so lost.

Sorry I'm not familiar with soap made in a blender. Yeah you definitely need to figure out how much soap your blender holds and go from there. What does your recipe look like? Also, what size bars do you like? I like mine 3.5 x 2.5 x1 inches, but you might like them more square or wider, etc.

My best suggestion without additional info would be to make it so the interior measures 3.5 x 2.5 x 8 inches and then have a couple additional mp molds standing by. Remember to tell your hubby interior measure, not exterior. That always threw me off in shop class lol!
