I finally made a semi-decent looking gradient soap. I was pretty happy with it until I took my kitchen knife to it and now I have 6 wonky bars that won't even stand up straight. I am a hobbyist so I should probably save my money but unfortunately the perfectionist in me cries every time the look of my soap is ruined by my helpless inability to cut in straight lines. I cannot seem to find a decent single-wire cutter in the UK. All the ones on Amazon have bad reviews and I am at a loss why soap making suppliers don't stock any. UK soapers- if you have any recommendations, please let me know.
