you'll want to resize each recipe you come across to your mold until you are able to have a variety of different sized molds. You will use soap calc to re-calculate your recipes. I just learned this last week with the help of others here, so i will share with you. You need to first determine how many ounces your mold holds. SO take the inner diameter length, times width, times depth, times .40. that will give you cubic ounces basically. You then go to the soap calc web page and on step two you will select ounces, then enter the number you came up with. Make sure that on step 6 (Or is it 8, it looks confusing) that you have % selected (it wont let you recalc a recipe based on ounces here). you will also need to know the percentages of all your oils used to do this. It takes someone smarter than me to convert ounces to percentages...... good luck and hope this helped.
