Unrole a small length and pres it gently along the back of a kitchen worktop. Unrole the roll to the length you want resting it on the worktop as you go. Cut off carefully at the point you want. If the item is sandwiches, cake or anything not needing further wrapping put that in the middle and pack it edge by edge. If putting on the top of a bowl, put it beside the bowl and lift up carefully by one side, one hand per corner and place over bowl.
I do not use much snapwrap as I put things in plastic containers, but for somethings (like my boat shaped glass bowl with the sides higher at the ends than in the middle), there is no substitution for snapwrap, mob caps and grease proof (bees wax or any other wax) do not flex sufficiently
