Cutting jellies

Hello All. I've been trying to make my own jellies for 2 years with no luck - the pectin formula that I used would never hold the shape. I just purchased Pectin from Burke Candy and it looks like it's working fine - finally! My next challenge will be to cut and enrobe them (enrobing by hand). Will a guitar cut jellies without sticking? Also, if I bottom the jelly slab will there be any problems cutting with a guitar? Will bottoming the slab make hand dipping possible? Thanks for the help. John
