made some blanks and was not paying attention and only did about 7 drops for 3 oz. of resin. Will I be able to save the blanks? It's okay if it takes longer as long as they will still harden.
You can put them in the sun for a couple hours and that will aid them in curing also. If you have a toaster oven, 150F will fix them in an hour or so also. I don't recommend you use the house oven though!
