Well I just cut with my serrated quik cut knife and worked good but they were still rather soft. then I molded them with my hands and smooted them out. However Vicki has seen them and no soap was on the outside of the loofa as my soap was too thick to pour right.
I cut with a straight bladed knife, thin one, and make a cut and then just push really hard with the knife while rolling soap and they cut pretty easy this way
I let mine get hard so no smoothing is needed, There is soap on the outside of mine, I try to pour at very thin trace with these..
I use a bread knife. Have one that is used for just that.. and it works great. Hardly any edges need smoothing.
Have learned though.. the loofah needs to just fit the tube... or so for me.
Makes a mess and it peels off the loofah when it dries.
We started with a serated knife, and it damages the loofa alot, so lots of smoothing on my part. Now husband who has freakishly strong hands simply cuts them with a cleaver. I have tried and I can not do it as thin or straight or pretty. If he ever decides to stop cutting my loofa, I will use my bandsaw. I am no weakling, but I can not cut these to save my life like he can. Vicki
