The idea is a good one about making my own knife using my dremel tool.
Being an 'ex' hairdresser/nail technician, I have one with all the attachments. Right now, couldn't find it if I wanted to however, as getting new kitchen renovation starting this morning. He's hammering away downstairs while I stay out of his way.
I'll pick one up if need be, at a Patio store or even in Lowes or some such place like that.
I will get Silpats. I promise not to get the knock off brand, as with anything else, it'd be inferior.
Thanks for the info and help.
