Mylar is a thin polyester film for lightweight, flexible stencils. It is useful for outlines, lettering and repeated marking. Its flexibility means the design must stay in place during use.
Keep internal shapes attached
Cut-out A, B and O letters leave loose internal pieces. Connect them to the stencil with material bridges. Do the same for enclosed openings in a logo. Read about paint stencil design to incorporate those connections.
Leave room to hold the film
Keep a border around the artwork for positioning. Large shapes and long narrow strips need more support than a compact symbol. Do not pull a fine connection to move the whole sheet.
Film can follow a curved substrate, but parts of the stencil can also lift away. Try the design on the actual surface with the chosen fixing method.
Plan alignment and repetition
A reference line, corner or alignment opening helps position a pattern consistently in several places. For multiple colours, make separate stencils sharing the same reference points.
Use and care
Test paint and cleaning on a small area. Paint build-up along edges changes the print and makes cleaning harder. Dry the film flat and store it without sharp folds.
See Mylar film for the available variant. For a stiffer template, compare suitable sheets in the plastics collection.
