it depends on how good you are at rebatching.
like everything else it takes practice, after all these years mine still leave something to be desired. they have the look of a slice of head cheese. i don't rebatch unless i have to and then i would just rather chunk or grate and toss it into a new batch of soap.
i'd google rebatched soap and click on some images.
oh and you don't need to use as much extra liquid as some of the soap books tell you to either. it depends on how old the soap base is.
i was afraid to make soap from scratch in the beginnin( same reason afraid of all the horror stories regarding lye ) and i researched and collected equipment for a year and then it all sat for a year before i decided i was just crazy, and if i gave it the respect it deserved and handled it properly i could do it. we got snowed in one weekend about this time of the year and i pulled everything out and made a small batch of soap, poured it into a plastic velvetta cheese container and insulated the day lights out of it, tucked it away, peeked at it every half and hour, was amazed at what i had made, and the next day unmolded it. nothing fancy, no color, no scent just basic plain jane soap made with cheap grocery store oils. been hooked every since.
so i know where you are coming from. i just wonder in amazement why anyone would ever rebatch on purpose,
when making soap from scratch is relatively easy once you get the hang of it. yes you'll have botched batches from time to time but i don't know of one seasoned soaper that still doesn't have a funky batch from time to time.
good luck in your soaping adventure.
